- 5 cups milk
- 1/4 teaspoon salt
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon paprika
- 1 teaspoon mustard powder
- 1/4 teaspoon red pepper flakes (optional)
- 1/2 cup sour cream (optional, but recommended)
- 2 cups sharp cheddar cheese, freshly grated
- 1 cup white Colby cheese (or mozzarella), freshly grated
- 1 cup Parmesan cheese, freshly grated
- 1 1/2 cups gluten-free buttery crackers (like Ritz), crushed into crumbs

- 1 cup white Colby cheese (or mozzarella), freshly grated (for topping)
- 1/2 cup cheddar cheese, freshly grated (for topping)
- 1/2 cup Parmesan cheese, freshly grated (for topping)
Instructions
- Step 1: Preheat the oven to 350 degrees F. Lightly grease a 9×13 baking dish with olive oil or non-stick cooking spray and set aside.
- Step 2: Cook the gluten-free pasta according to the box directions until al dente. Drain and rinse under hot water. Toss with olive oil in a large bowl to prevent sticking and set aside.
- Step 3: In a large saucepan over medium heat, melt 4 tablespoons of butter. Once melted, whisk in the gluten-free flour until fully combined to create a roux.
- Step 4: Gradually whisk in the milk, continuing until the mixture is smooth and fully combined.
- Step 5: Stir in onion powder, garlic powder, paprika, mustard powder, red pepper flakes (if using), and salt. Bring the mixture to a boil, then simmer for about 2 minutes, stirring frequently.
- Step 6: Remove from heat and stir in the sour cream until smooth. Taste and adjust seasoning with salt and pepper as needed.
- Step 7: Reduce heat to low and gradually stir in sharp cheddar, Colby, and Parmesan cheeses until melted and the sauce is creamy.
- Step 8: Add the cheese sauce to the cooked pasta and stir well to combine. Transfer the mixture to the prepared baking dish.
- Step 9: For the buttery cracker topping, mix crushed gluten-free buttery crackers with the melted butter until evenly coated.
- Step 10: Evenly sprinkle the remaining cheeses (Colby, cheddar, Parmesan) over the pasta, then top with the buttery cracker crumbs.
- Step 11: Bake uncovered for 25-30 minutes until the topping is golden brown and the sauce is bubbly.
- Step 12: Remove from the oven and let the casserole rest for 10-15 minutes before serving to allow it to set.
Tips & Variations
- Use freshly grated cheese for the best melting and flavor.
- For a creamier texture, add a splash of cream or half-and-half in place of some of the milk.
- Feel free to swap the white Colby cheese with mozzarella for a milder taste.
- To add a bit of protein, mix in cooked bacon or shredded rotisserie chicken before baking.
- If you prefer a spicy kick, increase the red pepper flakes slightly or add a dash of hot sauce to the cheese sauce.
Storage
Store any leftover mac and cheese in an airtight container in the refrigerator for up to 3 days. To reheat, cover with foil and warm in the oven at 350°F until heated through, or microwave in short intervals stirring in between. The topping may soften after refrigeration but will remain flavorful.

FAQs
Can I make this mac and cheese vegan or dairy-free?
This recipe relies heavily on cheese and butter for its creamy texture and rich flavor. For a vegan or dairy-free version, you can substitute dairy milk with plant-based milk and use vegan butter and cheese alternatives, but the taste and consistency may vary.
What type of gluten-free pasta works best?
Elbows or cavatappi work well as their shape holds the cheese sauce nicely. Look for high-quality gluten-free pasta made from rice, corn, or a blend for the best texture.
