Essential Ingredients for Chicken Spaghetti with Rotel
The beauty of this recipe lies in its simple, pantry-friendly ingredients. Here’s what you’ll need and why each component matters:
The Protein
Boneless, Skinless Chicken Breasts – About 2-3 pounds works perfectly for this recipe. You can also use leftover rotisserie chicken to save even more time—just shred it and skip the cooking step. Chicken thighs work beautifully too if you prefer darker meat with more flavor.
The Pasta
Spaghetti Noodles – I use about 12-16 ounces of regular spaghetti, cooked just to al dente. Don’t overcook the pasta since it’ll continue cooking in the oven. You can substitute with angel hair, linguine, or even penne if that’s what you have on hand.
The Flavor Base
Rotel Tomatoes – This is the star ingredient that makes this recipe special! Rotel diced tomatoes and green chilies come in both original and mild varieties. I typically use two 10-ounce cans, undrained, to ensure maximum flavor. The liquid from the cans helps create that perfect saucy consistency.
Cream of Chicken Soup – One 10.5-ounce can adds creaminess and depth. You can substitute cream of mushroom soup if preferred, or make a homemade version for a from-scratch approach.
The Cheese Trio
Velveeta Cheese – About 8-12 ounces, cubed. I know some people turn their noses up at Velveeta, but trust me—it’s what gives this casserole that impossibly smooth, creamy texture. It melts like a dream and doesn’t separate or get grainy.
Cream Cheese – A 4-8 ounce block adds richness and tang. Make sure it’s softened or cubed for easy melting.
Shredded Cheddar Cheese – About 1-2 cups for topping. I always grate my own from a block—it melts so much better than pre-shredded cheese, which contains anti-caking agents that can affect the texture.
Aromatics and Seasonings
- Garlic – 2-3 cloves, minced (or 1 teaspoon garlic powder in a pinch)
- Onion – One medium diced onion or 1 teaspoon onion powder
- Butter – 2-3 tablespoons for sautéing
- Salt and Black Pepper – To taste
- Optional: Cumin, chili powder, or taco seasoning – For extra southwestern flair
Smart Substitutions
- For a lighter version: Use reduced-fat cream cheese and reduced-sodium soup
- Gluten-free: Swap regular pasta for your favorite gluten-free variety and use gluten-free cream soup
- Vegetarian twist: Replace chicken with black beans, pinto beans, or extra veggies like bell peppers and mushrooms
- Dairy-free: Use dairy-free cream cheese and cheese alternatives (though the texture will be different)
- Extra veggies: Add diced bell peppers, corn, black beans, or spinach for more nutrition
How to Make Chicken Spaghetti with Rotel: Step-by-Step Instructions
Don’t let the ingredient list intimidate you—this recipe comes together surprisingly quickly. Here’s my foolproof method for perfect chicken spaghetti with Rotel every single time:
Step 1: Prep and Preheat
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish or a 3-quart casserole dish. I like to use cooking spray or a light coating of butter. Get your water boiling for the pasta—add a generous pinch of salt to the water for flavor.
Step 2: Cook the Pasta
Cook your spaghetti according to package directions, but aim for al dente (slightly firm to the bite). This is crucial because the pasta will continue cooking in the oven. Drain the pasta well and set aside. Pro tip: Reserve about 1 cup of pasta water before draining—you can use it to adjust the sauce consistency later if needed.
Step 3: Cook the Chicken
Cut your chicken breasts into bite-sized pieces (about 1-inch cubes work great). In a large skillet over medium-high heat, melt 2-3 tablespoons of butter. Add the diced onion and minced garlic, cooking for 2-3 minutes until fragrant. Add the chicken pieces, season with salt, pepper, and onion powder if using. Cook for 7-10 minutes, stirring occasionally, until the chicken is no longer pink inside and reaches 165°F internal temperature.
Time-Saving Hack: Using leftover rotisserie chicken? Skip this step entirely and just shred about 3-4 cups of cooked chicken. Add it directly to the sauce in the next step.
Step 4: Create the Creamy Sauce
This is where the magic happens! Reduce the heat to low. To the same skillet with your cooked chicken, add:
- Both cans of Rotel tomatoes (with their liquid—don’t drain!)
- One can of cream of chicken soup
- Cubed Velveeta cheese
- Cubed or softened cream cheese
Stir constantly over low heat until all the cheese melts into a smooth, creamy sauce. This takes about 5-7 minutes. Be patient and keep stirring—you don’t want the cheese to scorch on the bottom of the pan. The sauce should be thick, creamy, and coat the back of a spoon.
Step 5: Combine Everything
Add your drained spaghetti to the skillet with the chicken and cheese sauce. Using tongs or two large spoons, toss everything together until the pasta is completely coated with that gorgeous creamy sauce. Taste and adjust seasoning—this is your chance to add more salt, pepper, or even a dash of cumin or chili powder if you want more southwestern flavor.
If the mixture seems too thick, add a splash of that reserved pasta water or a bit of chicken broth to loosen it up. You want it creamy but not dry.
Step 6: Transfer and Top
Pour the entire mixture into your prepared baking dish, spreading it out evenly. Sprinkle the shredded cheddar cheese generously over the top. This creates that irresistible golden, bubbly cheese crust we all love.
Step 7: Bake to Perfection
Bake uncovered in your preheated 350°F oven for 25-30 minutes, until the cheese on top is melted, bubbly, and starting to turn golden brown around the edges. If you want an extra-crispy top, pop it under the broiler for the last 2-3 minutes—but watch it carefully so it doesn’t burn!
Step 8: Rest and Serve
Let the casserole rest for about 5 minutes after removing it from the oven. This allows the sauce to set slightly, making it easier to serve without everything sliding around. Garnish with fresh chopped cilantro, sliced green onions, or a dollop of sour cream if desired.

Pro Tips for the Best Chicken Spaghetti with Rotel
After making this recipe more times than I can count, I’ve picked up some tricks that guarantee perfect results every time:
- Don’t skip the al dente step: Seriously, slightly undercooked pasta is key. It’ll finish cooking in the oven and absorb some of that delicious sauce without turning mushy.
- Cube your cheese small: The smaller you cube the Velveeta and cream cheese, the faster and more evenly they’ll melt. I usually aim for 1/2-inch cubes.
- Use low heat for the sauce: High heat can cause the cheese to separate and become grainy. Low and slow wins the race here.
- Make it ahead: Assemble the entire casserole (minus the cheddar topping), cover tightly, and refrigerate for up to 24 hours. Add the cheddar just before baking, and add an extra 10 minutes to the bake time since it’s starting cold.
- Freeze for later: This recipe freezes beautifully! Assemble in a freezer-safe dish, cover tightly with plastic wrap and foil, and freeze for up to 3 months. Thaw overnight in the fridge before baking as directed.
- Adjust the spice level: Using mild Rotel? Add some diced jalapeños or a dash of hot sauce to kick it up. Using original Rotel but need it milder? Mix in some regular diced tomatoes to dilute the heat.
- Add extra veggies: Sauté bell peppers, mushrooms, or zucchini with the onions for more nutrition and flavor.
- Try different pasta shapes: While spaghetti is traditional, penne, rotini, or cavatappi work wonderfully and are easier for kids to eat.
Serving Suggestions and Pairings
This chicken spaghetti with Rotel is hearty enough to stand alone, but here are some fantastic accompaniments that take the meal to the next level:
Perfect Side Dishes

Storage and Reheating Instructions
One of the best things about this Rotel chicken pasta is how well it keeps and reheats:
Refrigerator Storage
Store leftovers in an airtight container in the refrigerator for up to 4 days. The flavors actually deepen and meld together overnight, making leftovers incredibly delicious. I often think this dish tastes even better on day two!
Freezer Storage
This casserole freezes beautifully for up to 3 months. You can freeze it before or after baking:
- Before baking: Assemble completely, cover tightly with plastic wrap and then aluminum foil, label with date, and freeze. Thaw overnight in fridge before baking as directed (add 10 extra minutes).
- After baking: Let cool completely, portion into individual servings or keep whole, wrap tightly, and freeze. Thaw in fridge overnight before reheating.
Reheating Methods
Oven method (best for maintaining texture): Preheat oven to 350°F. Cover the casserole with foil and bake for 20-25 minutes until heated through. Remove foil for the last 5 minutes to re-crisp the cheese topping.
Microwave method (quickest): Place individual portions in microwave-safe dishes. Cover with a damp paper towel and microwave on 50% power in 1-minute intervals, stirring between, until heated through. The lower power prevents the cheese from becoming rubbery.
Stovetop method: Place portions in a skillet over medium-low heat with a splash of chicken broth or water. Stir gently until heated through, about 5-7 minutes.
Recipe Variations to Try
Once you’ve mastered the basic recipe, have fun experimenting with these delicious variations:
Southwest Chicken Spaghetti Casserole
Add 1 can of black beans (drained), 1 cup of corn, 1 diced bell pepper, and a tablespoon of taco seasoning. Top with crushed tortilla chips mixed with the cheddar cheese before baking.
Chicken Alfredo with Rotel
Replace the cream of chicken soup with 1 cup of Alfredo sauce. Use white cheddar instead of regular cheddar, and add Italian seasoning. This gives you a creamy Italian-meets-southwestern fusion that’s absolutely divine.
Crockpot Chicken Spaghetti with Velveeta
Cook chicken in the crockpot on low for 4 hours, shred it, then add all other ingredients except pasta. Cook on low for 2 more hours. Cook pasta separately and stir in just before serving. This method is perfect for busy days!
Fireman Spaghetti
Add diced jalapeños, use hot Rotel, mix in some pepper jack cheese, and top with extra cayenne pepper. This version lives up to its spicy name!
Mexican Chicken Spaghetti
Add a packet of taco seasoning, black beans, corn, and diced bell peppers. Top with a mixture of cheddar and Monterey Jack cheese. Serve with tortilla chips and salsa on the side.
Chicken Enchilada Spaghetti
Replace the cream of chicken soup with red or green enchilada sauce. Add cumin and chili powder. Top with a mixture of Mexican blend cheese and serve with sour cream and fresh cilantro.
Frequently Asked Questions
Can I make chicken spaghetti with Rotel ahead of time?
Absolutely! This is actually one of the best make-ahead casseroles. Assemble the entire dish up to 24 hours in advance, cover tightly, and refrigerate. When ready to bake, add the cheese topping and bake as directed, adding an extra 10-15 minutes since it’s starting cold. You can also freeze it unbaked for up to 3 months.
Can I use chicken thighs instead of chicken breasts?
Yes! Chicken thighs add even more flavor and stay moist during baking. Use the same amount of boneless, skinless thighs as you would breasts. Just note that thighs take slightly longer to cook through—about 10-12 minutes instead of 7-10.
What can I substitute for Velveeta cheese?
While Velveeta creates the smoothest, creamiest sauce, you can substitute with 2 cups of shredded American cheese or a combination of cream cheese and extra cheddar. The texture will be slightly different—not quite as smooth—but still delicious. Add a tablespoon of cornstarch mixed with a bit of milk to help the cheese stay creamy.
Is Rotel the same as diced tomatoes?
Not quite! Rotel is a brand of diced tomatoes that includes green chilies (either mild or original heat level). If you can’t find Rotel, you can substitute with regular diced tomatoes plus a 4-ounce can of diced green chilies. However, Rotel has a distinct flavor that really makes this dish special, so I recommend seeking it out.
How do I keep the pasta from getting mushy?
The key is cooking the pasta just to al dente (slightly firm) before adding it to the casserole. Since it continues cooking in the oven while absorbing the sauce, starting with slightly undercooked pasta ensures perfect texture in the final dish. Also, don’t overbake—25-30 minutes is plenty.
Can I make this gluten-free?
Yes! Simply swap regular pasta for your favorite gluten-free variety and use gluten-free cream of chicken soup (or make your own with gluten-free flour). Everything else in the recipe is naturally gluten-free. Just check your Rotel label to confirm.
Why is my cheese sauce grainy or separated?
This usually happens when cheese is melted over too high heat. Always use low heat and stir constantly when melting the cheese. If your sauce does separate, try whisking in a tablespoon of cornstarch mixed with a little milk—this often brings it back together.
Can I double this recipe?
Definitely! This recipe doubles beautifully and is perfect for feeding a crowd or making multiple casseroles to freeze. Use a large roasting pan or two 9×13-inch baking dishes. The baking time remains the same.
What’s the best way to reheat leftovers?
For best results, reheat in the oven at 350°F covered with foil for about 20 minutes. For quicker reheating, use the microwave on 50% power to prevent the cheese from becoming rubbery. Adding a splash of chicken broth or milk when reheating helps restore the creamy texture.
Can I add vegetables to this recipe?
Absolutely! Diced bell peppers, mushrooms, spinach, corn, and black beans all work wonderfully. Sauté firmer vegetables like peppers and mushrooms with the onions before adding the chicken. Add corn, beans, or spinach directly to the sauce.
