Key Ingredients & Substitutions
Pasta: Elbow macaroni is a classic choice, but feel free to swap it for any pasta you love—penne, shells, or even gluten-free pasta work great too!
Rotel Diced Tomatoes: The star of the dish! If you want a milder flavor, try using plain diced tomatoes with green chilies or even regular diced tomatoes and add a sprinkle of chili powder.
Cheeses: Cheddar adds a lovely sharpness, but you can mix it up! Try using Monterey Jack, Colby, or a blend for different flavors. For a vegan option, substitute with plant-based cheese or nutritional yeast.
Milk: Whole or 2% milk gives the best creaminess, but almond milk or oat milk are good dairy-free alternatives if you’re looking for a lighter version.
How Do I Make a Smooth Cheese Sauce Without Lumps?
Making a smooth cheese sauce can be tricky, but it’s all about the technique. Start by making a roux with butter and flour. Cook it briefly to eliminate any floury taste, then add milk slowly while whisking.
- Keep the heat at medium to ensure the mixture thickens without burning.
- Whisk constantly as you add the milk to prevent lumps. If lumps do start to form, keep whisking or switch to a whisk to help break them up.
- Once your sauce is smooth, gradually mix in the cheese until it’s melted and creamy.
Patience is key here, so take your time and enjoy the process!

Step-by-Step Instructions:
1. Cook the Pasta:
Begin by boiling water in a large pot. Once boiling, add the elbow macaroni and cook according to the package directions until al dente, usually around 7-9 minutes. Drain the pasta and set it aside, making sure it’s nice and ready to soak up that creamy sauce!
2. Make the Roux:
In a medium saucepan, melt the butter over medium heat. Once melted, sprinkle the flour over it and whisk briskly for about 1 minute to form a roux. This will help thicken your cheese sauce!
3. Create the Cheese Sauce:
Gradually whisk in the milk, stirring constantly to keep the mixture smooth. Continue to cook for about 3-5 minutes, or until the sauce begins to thicken slightly. Be patient, and make sure to keep stirring!
4. Add the Cream Cheese:
Turn the heat down to low and stir in the softened cream cheese. Keep mixing until it’s fully melted and blended into the sauce for a rich creaminess.
5. Stir in the Cheddar Cheese:
Add the shredded cheddar cheese to the mixture and stir until it’s completely melted and your sauce is wonderfully cheesy!
6. Mix in the Rotel:
Next, add the undrained Rotel diced tomatoes, garlic powder, onion powder, salt, and pepper to the cheese sauce. Stir everything together and let it heat through for about 2-3 minutes. The flavors will combine beautifully!
7. Combine with Pasta:
Pour the creamy cheese and Rotel sauce over the drained pasta. Mix well to coat every piece evenly with that delicious cheesy goodness.
8. Garnish and Serve:
If you like, sprinkle some chopped green onions or fresh cilantro on top for a pop of color and freshness. Serve the pasta warm, and enjoy your scrumptious meal!
Enjoy your creamy, cheesy Rotel pasta, perfect for a comforting dinner!
