  • Hearty ingredients deliver a nourishing and filling meal in every bite.

Ingredients

  • Ground beef (1 lb): Provides rich, savory protein as a hearty foundation for the chili mac.
  • Kidney beans (1 can, 15 oz): Adds creaminess and fiber, complementing the meat with a mild texture.
  • Diced tomatoes (1 can, 28 oz): Offers tangy acidity and moisture, balancing flavors and blending well in the crockpot.

  • Garlic (2 cloves, minced): Adds depth and a subtle spicy punch that complements beef and tomatoes.

  • Cheddar cheese (2 cups, shredded): Melted into the dish to create a luscious, gooey texture and sharp cheesy flavor.

  • Salt and pepper (to taste): Essential seasonings to balance and enhance all other flavors.

Instructions

Brown the Ground Beef and Onion

In a skillet over medium heat, cook the ground beef with chopped onion until beef is browned and onions are translucent. Drain excess fat to prevent greasiness, then transfer the mixture to the crockpot. This step builds flavor and ensures the beef is fully cooked before slow cooking.

Add Remaining Ingredients Except Cheese

Add kidney beans, diced tomatoes, minced garlic, uncooked elbow macaroni, chili powder, salt, and pepper into the crockpot with the beef mixture. Stir gently to combine all ingredients evenly. This prepares the dish to cook together slowly, allowing flavors to meld impeccably.

Cook on Low for 4-5 Hours

Cover and cook the mixture on the low setting of your crockpot for 4 to 5 hours. This slow cooking tenderizes the pasta and lets the chili flavors deepen, creating a hearty and comforting meal without needing much attention.

Stir in Cheddar Cheese Before Serving

About 15 minutes before serving, stir in the shredded cheddar cheese until fully melted. This adds creamy richness and a deliciously gooey texture that ties the whole dish together beautifully.

You Must Know

  • Using uncooked pasta in the crockpot saves time and blends flavors but avoid overcooking to keep pasta from becoming mushy.
  • Feel free to adjust chili powder to suit your spice preference or add other seasonings like cumin for extra warmth.
  • For a thicker chili mac, reduce the amount of diced tomatoes or add a tablespoon of tomato paste.

Storage Tips

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stove or in the microwave, adding a splash of milk to restore creaminess if needed.

Serving Suggestions

This chili mac and cheese pairs wonderfully with a crisp green salad or steamed vegetables for a balanced meal. Garnish with fresh herbs or a dollop of sour cream to elevate the presentation and flavor experience.

Professional Tips

  • Brown the beef thoroughly to develop rich umami flavors before slow cooking.
  • Use sharp cheddar for pronounced cheesiness or blend with Monterey Jack for a smoother melt.
  • If your crockpot runs hot, check pasta tenderness at 3 hours to prevent overcooking.

FAQs

Can I use a different type of pasta?

Yes, short pasta shapes like rotini or shells also work well, but adjust cooking time as needed for tenderness.

Is it possible to make this vegetarian?

Absolutely! Substitute ground beef with plant-based crumbles or extra beans and add vegetables like bell peppers for more texture.

Can I prepare this recipe in advance?

How spicy is this chili mac and cheese?

Mild to moderate heat depending on chili powder amount; easily adjusted to taste to suit all palates.

Can I freeze leftovers?

Freezing is possible but pasta texture may change slightly. For best results, freeze without cheese and add fresh after reheating.

What type of cheddar cheese works best?

A sharp or medium cheddar melts well and provides the classic strong cheesy flavor that complements chili perfectly.

Can I add more vegetables?

Definitely! Diced bell peppers, corn, or zucchini can be added along with the other ingredients for extra nutrition and flavor.
