Ingredients You’ll Need

- Gluten-free pasta: Use any type of pasta you prefer! I used Jovial for this recipe.
- Leftover chili: You can use beef, turkey, or even a vegetarian mix.
- Cottage cheese: Blended into the sauce for creaminess and extra protein. Ricotta works as a swap if desired.
- Milk of choice: Helps create a smooth, velvety cheese sauce. Almond, oat, or regular dairy milk all work.
- Cornstarch: Thickens the sauce to coat the pasta perfectly. Xanthan gum is another option.
- Shredded sharp cheddar cheese: If you’re dairy-free, feel free to swap in a plant-based alternative for the same gooey, comforting texture.
- Seasonings: Salt, black pepper, garlic powder, paprika, and onion powder help make the flavor of this chili mac bold and delicious.
- Toppings: A dollop of sour cream or Greek yogurt and fresh green onions complete the dish.
How to Make Leftover Chili Mac
Step 1: Preheat the oven to 375°F (190°C) and grease a baking dish (or casserole dish). Cook pasta (gluten-free or regular) in a large pot according to package directions; drain.
Step 2: In a blender, combine cottage cheese, milk, cornstarch, 1 cup of the shredded cheese, salt, pepper, garlic powder, paprika, and onion powder. Blend until smooth.
Step 3: Pour the blended sauce into a pot or medium saucepan and heat over medium-high heat for 2-3 minutes, stirring until slightly thickened.
Step 4: Stir in the cooked pasta and mix to combine.
Step 5: Transfer to the prepared baking dish.
Step 6: Top with the leftover chili and lightly mix in.
Step 7: Sprinkle the remaining shredded cheese on top.

Step 8: Bake for 15-20 minutes, or until the cheese is melted and bubbly. Garnish with a dollop of Greek yogurt and green onions.
