This recipe is a celebration of simple, family-friendly ingredients that come together with minimal effort for a meal that’s as satisfying as it is delicious.

Ingredients:
For the Casserole:*
1 pound ground beef (80/20 recommended)
1 medium onion, chopped
2 cloves garlic, minced
1 (14.5 oz) can diced tomatoes, undrained
1 (10.75 oz) can condensed tomato soup
2 cups shredded cheddar cheese, divided
2 cups elbow macaroni (uncooked)
1 teaspoon dried oregano
1 teaspoon dried basil
Salt and pepper, to taste
Instructions:
Step 1: Brown the Beef*
In a large skillet over medium heat, cook the ground beef, onion, and garlic until the beef is browned and the onion is tender, about 6-8 minutes. Break the meat apart with a spoon as it cooks. Drain any excess fat.
Step 2: Combine in Slow Cooker*
Transfer the beef mixture to a 4-6 quart slow cooker. Stir in the diced tomatoes (with their juices), tomato soup, 1 cup of the shredded cheddar cheese, uncooked elbow macaroni, oregano, basil, salt, and pepper. Stir until everything is well combined.
Step 3: Cook*
Cover and cook on LOW for 4-5 hours, or until the macaroni is tender and the flavors have melded.
Step 4: Add the Remaining Cheese*
Sprinkle the remaining 1 cup of cheddar cheese over the top of the casserole. Cover and cook for an additional 15-20 minutes, until the cheese is melted and bubbly.
Step 5: Serve*
Serve hot, straight from the slow cooker.
Tips:
- Brown the Beef First: This step adds depth of flavor and ensures the beef is fully cooked and the fat is drained.
- Use Sharp Cheddar: Sharp cheddar adds a bold, tangy flavor that stands up well to the tomato sauce.
- Don’t Overcook: Check the macaroni at the 4-hour mark — if it’s tender, it’s ready. Overcooking can make the pasta mushy.
- Add Vegetables: For extra nutrition, stir in a cup of frozen peas or chopped bell peppers with the beef.
- Stir Halfway: If possible, give the slow cooker a quick stir halfway through to ensure the pasta cooks evenly.
Serving Suggestions:
- Serve with a side salad and garlic bread.
- Garnish with fresh parsley or extra shredded cheese.
- Pair with a glass of your favorite red wine.
Storage Options:
- Refrigerator: Store leftovers in an airtight container in the refrigerator for up to 4 days.
- Reheating: Reheat in the microwave or in a covered skillet over low heat. Add a splash of milk or broth to loosen the sauce if needed.
- Freezer: This dish freezes well for up to 2 months. Cool completely, transfer to a freezer-safe container, and freeze. Thaw overnight in the refrigerator before reheating.
- Make-Ahead: Assemble the casserole in the slow cooker insert (without cooking), cover, and refrigerate overnight. Cook as directed the next day, adding 30-60 minutes to the cooking time.
