How to Make It
After years of testing slow cooker pasta dishes, the single most important step is browning the beef first it prevents a watery texture and builds real depth of flavor. Don’t skip it.
- In a large skillet, brown and crumble the ground beef with the chopped yellow onion until no pink remains and the onion turns translucent. Drain off excess fat.
- Transfer the beef and onion mixture to a 3 to 6 quart slow cooker.
- Add the uncooked elbow macaroni, canned diced tomatoes (undrained), taco seasoning mix, and water. Stir to combine.
- Cover and cook on LOW for 4 to 5 hours, until the pasta is tender and cooked through.
- Turn the slow cooker off. Stir in the shredded cheddar cheese and let it sit for 10 minutes to melt completely before serving.
Pro Tip: Giving it one good stir about halfway through if you’re home helps the pasta cook evenly and keeps the edges from drying out.
