Ingredients You’ll Need

• 1 tablespoon olive oil: To brown the beef and aromatics.
• 1 pound lean ground beef: Our hearty, protein-packed base.
• 1 medium yellow onion, diced: Adds a sweet, savory foundation.
• 2 cloves garlic, minced: For that essential aromatic punch.
• 4 cups low-sodium beef broth: Creates the flavorful cooking liquid for the pasta.
• 1 (15 oz) can tomato sauce: Brings a touch of tangy sweetness.
• 1 teaspoon Italian seasoning: A simple blend for herby depth.
• ½ teaspoon salt, plus more to taste: To season every layer.
• ¼ teaspoon black pepper: For a little kick.
• 1 (12 oz) box medium pasta shells: Their shape is perfect for capturing the sauce.
• 2 cups shredded sharp cheddar cheese: For that irresistible, melty goodness.
• ½ cup milk or half-and-half: Loosens the cheese into a creamy sauce.
• Optional garnish: Fresh chopped parsley.

Let’s Get Cooking Step by Step

1. Brown the Beef: In a large pot or Dutch oven, heat the olive oil over medium-high heat. Add the ground beef and onion. Cook, breaking up the meat with a spoon, until the beef is no longer pink and the onion is soft, about 5-7 minutes. Stir in the garlic and cook for one more minute until fragrant.
2. Build the Sauce: Drain off any excess grease from the pot. Pour in the beef broth and tomato sauce. Add the Italian seasoning, salt, and pepper. Give everything a good stir, scraping up any browned bits from the bottom of the pot—that’s pure flavor!
3. Cook the Pasta: Bring the liquid to a boil. Stir in the uncooked pasta shells. Reduce the heat to a steady simmer, cover the pot, and let it cook for about 12-15 minutes, stirring occasionally to prevent sticking. The pasta should be al dente and most of the liquid absorbed.
4. Create the Cheese Sauce: Turn the heat down to low. Stir in the shredded cheddar and milk until the cheese is completely melted and the sauce is smooth and creamy. Taste and adjust seasoning if needed. If the sauce seems too thick, you can add another splash of milk or broth.
5. Serve and Enjoy: Let it sit for a couple of minutes off the heat to thicken up slightly. Dish it up hot, garnished with a little parsley if you like!

One-Pot Cooking Tips for Success

• Don’t skip the step of scraping the browned bits from the bottom of the pot when you add the liquid. It adds a ton of flavor.
• Stir occasionally while the pasta is cooking to ensure it cooks evenly and doesn’t clump together.
• Use a good, block-style cheddar you shred yourself for the best melt. Pre-shredded cheese often has anti-caking agents that can make the sauce a bit grainy.
• If you’re in a super big hurry, you can use a smaller pasta like elbow macaroni or rotini—they’ll cook a minute or two faster.
• Honestly, the worst thing you can do is walk away and forget about it. Set a timer so your pasta doesn’t go from perfect to mush.
• And remember, all stoves are different! If the liquid is absorbing too fast, add a little more broth. If it’s too soupy, just let it simmer uncovered for a few more minutes.

Variations & Substitutions

This recipe is a fantastic canvas for your own creativity! For a lighter twist, swap the ground beef for ground turkey or chicken. Want to add some veggies? Toss in a cup of frozen peas, chopped spinach, or diced bell peppers with the pasta. If you’re looking for a flavor change, try using a Mexican-style cheese blend and adding a can of mild green chiles for a southwest kick. For a richer sauce, use half-and-half instead of milk. And if you’re out of tomato sauce, a can of diced tomatoes (undrained) works in a pinch, though the texture will be a bit chunkier.

Storage & Reheating Instructions

Leftovers are almost better the next day! Let the dish cool completely before storing. It will keep in an airtight container in the refrigerator for up to 4 days. To reheat, the microwave is easiest—just place a portion in a bowl, splash in a tablespoon of water or broth, cover, and heat in 30-second intervals, stirring in between, until hot. You can also reheat it gently in a saucepan on the stove over low heat, again adding a little liquid to loosen the sauce. I don’t recommend freezing this one, as the dairy-based sauce can become grainy when thawed.

Serving Ideas & Pairings

This One-Pot Beefy Cheddar Shells dish is a complete meal all on its own, but it’s wonderful with a simple side. A crisp green salad with a tangy vinaigrette is my go-to to balance the richness. Some garlic bread or a crusty baguette is never a bad idea for soaking up any extra sauce. For a veggie side, try some steamed green beans or roasted broccoli. It’s one of those dinner meals that just feels like a hug in a bowl.
