Preparation Steps
- Preheat the oven to 350°F and lightly grease a 9x13 baking dish with olive oil or non-stick cooking spray.
- Prepare the pasta according to package directions until al dente. Drain and run under hot water, then mix with olive oil and set aside.
- In a large saucepan over medium heat, melt the unsalted butter. Add in the gluten-free flour and whisk until combined. Gradually whisk in the milk.
- Stir in onion powder, garlic powder, paprika, mustard powder, optional red pepper flakes, and salt. Bring to a boil and simmer for about 2 minutes.
- Mix in the sour cream, then taste and adjust the seasoning. Reduce the heat to low and add sharp cheddar, Colby, and Parmesan. Stir until melted.
- Pour the cheese sauce over the cooked pasta in a large bowl, mixing until well combined. Transfer the mixture to the greased casserole dish.
- If using, mix the crushed gluten-free buttery crackers with melted butter, then sprinkle it over the pasta mixture.
- Sprinkle the remaining cheese (Colby, cheddar, and Parmesan) over the top of the casserole.
- Place the dish in the oven and bake uncovered for 25-30 minutes until golden brown and bubbly. Let it rest for 10-15 minutes before serving.
Notes
For best results, use freshly grated cheese and let the dish sit before serving for improved sliceability. This dish can be made ahead of time and stored for easy reheating. Experiment with veggie additions for extra nutrition.
