Cook Mode Prevent your screen from going dark

Instructions

In a large skillet over medium-high heat, cook the ground beef and diced onion until the beef is browned. Drain any excess grease and stir in the garlic for 30 seconds.
Transfer the beef mixture to a 6- or 7-quart slow cooker.
Add the marinara sauce, tomato sauce, tomato paste, beef broth, Worcestershire sauce, Italian seasoning, garlic powder, onion powder, paprika, salt, black pepper, and crushed red pepper flakes. Stir well.
Cover and cook on LOW for 4–5 hours or HIGH for 2–3 hours.
Stir in the uncooked elbow macaroni. Cover and continue cooking for 25–35 minutes, stirring once halfway through, until the pasta is tender.
Turn the slow cooker to Warm. Stir in the cheddar cheese and Parmesan until melted and creamy.
Sprinkle with fresh parsley and serve immediately.

Notes

Freshly shredded cheese melts much smoother than pre-shredded cheese.
If your sauce becomes too thick after adding the pasta, stir in a splash of beef broth.
Cook the pasta only until al dente to prevent it from becoming mushy.
Want an extra creamy version? Stir in 4 ounces of cream cheese with the cheddar.
Leftovers taste even better the next day.

Make It Your Own

Add diced mushrooms or bell peppers.
Stir in spinach during the last 5 minutes.
Use ground turkey or Italian sausage instead of beef.
Swap cheddar for Colby Jack, mozzarella, or Pepper Jack.
Sprinkle extra Parmesan on top before serving.

Frequently Asked Questions

Can I use a different pasta?

Yes! Small shells, rotini, cavatappi, or penne all work well.

Can I cook the pasta separately?

Absolutely. If you prefer firmer pasta, cook it separately and stir it into the finished sauce with the cheese.

Can I make this ahead?

Yes. Prepare the meat sauce a day ahead, refrigerate, then finish with the pasta and cheese before serving.

Can I use ground turkey?

Yes. Ground turkey or ground chicken both make great lighter alternatives.

Make It Your Own

Stir in pepperoni for a pizza-inspired version.
Add cooked bacon for smoky flavor.
Mix in ricotta for a lasagna-style twist.
Top with buttery toasted breadcrumbs before serving.
Add extra cheddar on top and broil individual servings for a bubbly cheese crust.

Recipe Tips

Browning the beef first adds much more flavor.
Keep the lid closed while the pasta cooks.
Shred cheese fresh instead of using pre-shredded.
Let the Beef-A-Roni rest for 5 minutes before serving so the sauce thickens beautifully.
