Ingredients

This Cheesy Chili Mac Casserole keeps things wonderfully simple.

For the base, you’ll need cooked ground beef and al dente elbow macaroni — the pasta should have a little bite left since it finishes in the oven. For the sauce and topping, canned chili with beans, condensed cheddar cheese soup, and shredded sharp cheddar do all the heavy lifting.

Amount	Ingredient
1 lb	Ground beef
12 oz	Elbow macaroni, cooked to al dente and drained
1 (15 oz) can	Chili with beans
1 (10.5 oz) can	Condensed cheddar cheese soup
2 cups	Shredded sharp cheddar cheese

Tools You’ll Actually Use

No fancy equipment needed here — just the basics you already have in your kitchen.

• Large skillet or saute pan (for browning the beef)
• Large pot (for boiling the macaroni)
• Colander (for draining pasta and beef)
• 9×13-inch baking dish, greased
• Wooden spoon or silicone spatula
• Oven (preheated to 375 degrees F)

Step-by-Step Instructions for This 5-Ingredient Cheesy Chili Mac Casserole

Follow these easy steps and you’ll have a bubbling, cheesy dinner on the table in no time.

Step 1: Brown the Beef

Heat a large skillet over medium-high heat. Add 1 lb of ground beef and cook, breaking it into small crumbles with a wooden spoon, until fully browned with no pink remaining — about 7 to 9 minutes.

Drain the excess grease from the skillet and return the browned beef to the pan. This keeps the sauce from turning greasy.

Step 2: Make the Sauce

Stir one 15 oz can of chili with beans and one 10.5 oz can of condensed cheddar cheese soup directly into the skillet with the browned beef.

Mix over medium heat until the chili and soup are fully combined and the mixture is thick, smooth, and heated through — about 2 to 3 minutes. It should look saucy but not watery.

Step 3: Add the Pasta

Fold 12 oz of cooked, drained al dente elbow macaroni into the chili-beef sauce.

Stir gently until every piece of pasta is evenly coated. The mixture should be thick and hearty — not dry or soupy. If it looks dry, the pasta may have been overcooked, so aim for firm pasta next time.

Step 4: Assemble the Casserole

Transfer the entire pasta mixture into a greased 9×13-inch baking dish and spread it out evenly with a spatula so everything bakes uniformly.

Step 5: Top with Cheese

Sprinkle 2 cups of shredded sharp cheddar cheese in an even layer across the entire surface of the casserole. Make sure you get full coverage — every bite deserves that cheesy top.

Step 6: Bake

Bake uncovered in a preheated 375 degrees F (190 degrees C) oven for 20 to 25 minutes, until the cheddar is fully melted and glossy.

You’re looking for melted and shiny, not browned or bubbling at the edges. Pulling it out at glossy is the sweet spot for this casserole.

Step 7: Rest Before Serving

Let the casserole rest on the counter for 5 to 10 minutes before scooping and serving. This allows it to set up so portions hold together nicely and don’t fall apart on the plate.

Pro Tips for the Best Chili Mac Casserole

A few small tricks make a big difference with this Chili Mac Casserole.

The biggest one? Don’t skip the resting time. It sounds fussy, but those 5 to 10 minutes really do help the whole thing set up properly.

Cook your pasta to al dente — not soft. The macaroni continues cooking in the oven, so if it’s already soft before baking, it’ll turn mushy in the final dish. Firm pasta holds up perfectly.

Use sharp cheddar, not mild. The stronger flavor of sharp cheddar stands up beautifully against the bold chili base. Mild cheese can get lost in all that savoriness.

Don’t drain the chili before adding it. That liquid is flavor. It helps create the saucy, cohesive texture you want in every bite.

Let the cheese melt to glossy, not brown. Overbaking dries out the cheese and makes the pasta stiff. Pull it when the cheese looks melted and shiny — that’s your signal.

Quick Fixes for 5-Ingredient Cheesy Chili Mac Casserole

Even simple recipes have off days. Here’s how to fix common hiccups.

The casserole looks dry after baking. This usually means the pasta was overcooked before it went into the oven. Next time, cook the macaroni 1 to 2 minutes less than the package suggests. You can also stir a splash of water or broth into the mixture before transferring to the baking dish.

The cheese didn’t melt evenly. This happens when cheese is clumped rather than spread in an even layer. Before baking, use your fingers to break up any thick piles and distribute the cheddar across the entire surface.

The sauce feels too thick before baking. No problem — stir in two to three tablespoons of water or beef broth to loosen it up slightly. It should be saucy but not stiff when you fold in the pasta.

The bottom is sticking to the baking dish. Make sure you grease the dish thoroughly before adding the mixture. A light coating of cooking spray or butter on the bottom and sides does the trick every time.

It came out bland. Condensed cheddar cheese soup can vary by brand. If yours is on the milder side, add a pinch of garlic powder, onion powder, or smoked paprika to the sauce before baking for a flavor boost.

Variations and Adaptations

This Cheesy Chili Mac Casserole is wonderfully flexible. Here are some fun ways to make it your own.

Spicy version: Use a can of hot chili with beans instead of regular, or stir in a pinch of cayenne and a few dashes of hot sauce when making the sauce.

Turkey swap: Ground turkey works beautifully here in place of beef for a slightly lighter spin. Season it with a little garlic powder and onion powder since turkey is milder than beef.

Extra veggie boost: Fold in a can of drained black beans, a handful of frozen corn, or some diced green chiles along with the pasta for extra color and nutrition.

Gluten-free: Swap in your favorite gluten-free elbow pasta. Just check that your canned chili and condensed soup are also gluten-free — most are, but it’s worth a quick label check.

Cheesy topping remix: Try a blend of cheddar and Pepper Jack for a little heat and meltiness, or use Colby Jack for a milder, creamier top layer.

Serving, Storage, and Reheating

This Chili Mac Casserole is a hearty all-in-one meal, but a few simple sides round it out nicely.

Serve it with a simple green salad, a side of buttered cornbread, or some warm tortilla chips on the edge of the plate. Sour cream, sliced scallions, and pickled jalapenos make great optional toppings for people who love to customize their bowl.

Leftovers keep well in an airtight container in the refrigerator for up to 4 days. The flavor actually deepens overnight, so day-two portions are genuinely delicious. This also makes it a wonderful meal-prep option for the week ahead.

To reheat, add a splash of water or broth to your portion before microwaving to keep it from drying out. Microwave on medium power in 60-second increments, stirring between each, until heated through. You can also reheat it in a covered baking dish at 350 degrees F for about 15 minutes for a larger batch.

No-Waste Kitchen Magic

Love it when nothing goes to waste? Here are some creative ways to use up every last bit of this casserole.

Chili Mac stuffed peppers: Scoop leftover casserole into halved bell peppers, top with a little extra cheese, and bake at 375 degrees F for 20 minutes. Totally different meal, zero extra effort.

Loaded chili mac nachos: Spread leftover casserole over tortilla chips on a sheet pan, add more cheese, and broil for 3 to 5 minutes until bubbly. Finish with sour cream and salsa for a fun snack.

Chili mac soup: Thin out leftovers with beef broth, warm on the stovetop, and you’ve got a hearty, chunky soup for lunch the next day.

Freezer-friendly portions: Spoon cooled leftovers into individual freezer-safe containers and freeze for up to 3 months. Thaw overnight in the fridge, then reheat as usual for an instant dinner on the most exhausted of evenings.
