Ingredients to make Mac and Cheese with Chili

- Ground beef: I prefer to use 85% lean ground beef for flavor and not too much fat. Ground turkey or chicken will work
- Pasta: Small pasta shells like wagon wheels, shells, elbow, or any small pasta tubes.
- Fire-roasted diced tomatoes: Fire-roasting gives a robust flavor. Regular diced tomatoes can be used.
- Chili beans: Canned beans in chili sauce to bring another level of flavor to the ingredients. Found in the bean section of local grocers.
- Red Pepper: Use any color pepper you have in the refrigerator.
- Spices: They enhance the flavors.

How to store Chili Macaroni
Storage - Leftovers can be kept in the refrigerator in an airtight container for up to 3 days.
Make-Ahead and Freezer Instructions - Make a double batch and freeze a tray for a later date.
The casserole can be cooked and cooled before freezing. Do not add the cheese topping. Freeze in a freezer-safe container or well-wrapped in plastic wrap and foil to avoid freezer burn.
Eileen's Tips for the Best Chili Cheese Macaroni
- As a one-pot ground beef pasta dinner, use a large skillet to hold all the ingredients.
- Be sure to drain off and discard excess fat from the meat after browning.
- The spice level is mild. Start with the spices in the recipe. As it simmers, taste, and add seasoning if you prefer a higher spice level.
- To freeze the chili mac, let it cool completely. Store in freezer-safe bags or containers. Defrost in the fridge overnight and warm in a pot over a slow simmer. The pasta can be warmed in the oven in a covered dish at 325°F for about 20 minutes until the pasta is warmed through.
- Keep leftovers in the fridge for up to 3 days well covered. Always best to refer to USDA for any reference guide to leftovers and storage
Change Up Chili Cheese Mac
Do you want to change up this recipe? Here are some ways to change the flavor of this dish.
- Protein: Change up the meat, use ground turkey, chicken, pork, or ground sausage. Prefer vegan, use veggie crumbles or diced mushrooms instead of meat.
- Beans: Chili beans are our favorite but other beans such as black or red can be used. You may want to increase the spices if using plain beans.
- Vegetarian: Use meatless crumbles or lentils instead of the ground beef. Also use vegetable stock instead of beef stock.
- Gluten-Free: Use a gluten-free pasta. I have recipe tested with Barilla and it works well.
- Corn: Add 8 ounces of either frozen, thawed corn or canned corn drained.
- Cheese: We use a combo of Colby Jack and cheddar. You can use all cheddar or any of your favorite melting cheeses.
