How to Make Dump-and-Go Crockpot Pizza Pasta Casserole

Handsfree mode (keeps screen awake)

Build the sauce base

Add the ground beef, marinara, broth, garlic powder, bouillon, Italian seasoning, salt, and pepper to the slow cooker.
Break the beef into small pieces so it cooks evenly and blends into the sauce.
Cook until the beef is done

Cover and cook on HIGH for 2 to 3 hours, or on LOW for 4 to 5 hours.
Stir once or twice if you can, and make sure the beef reaches 160°F.

Add the pasta

Stir in the rotini once the beef is fully cooked and the sauce is bubbling.
Press the pasta under the liquid, then cover and cook on HIGH for 20 to 30 minutes.
Melt the cheese and pepperoni

When the pasta is tender, stir in half the mozzarella for a creamier texture.
Top with the remaining mozzarella, cheddar, and pepperoni.
Cover for 5 to 10 minutes, until the cheese melts.
Rest and serve

Let the casserole stand for 5 minutes before serving.
This short rest helps the sauce thicken and keeps the pasta from sliding apart.

Substitutions

Ground beef for Italian sausage: Italian sausage adds extra seasoning and stronger pizza-shop flavor. Use mild or hot, and reduce the added salt slightly.
Rotini for penne or cavatappi: Both shapes hold sauce well and keep a good bite in the slow cooker. Cavatappi makes the dish especially fun.
Pepperoni for turkey pepperoni or veggie pepperoni: Turkey pepperoni keeps the smoky flavor with less richness. Veggie pepperoni works well and still gives classic pizza-night vibes.

Tips

Use lean beef: Lean beef leaves less grease in the sauce. If your beef is fatty, brown and drain it first.
Watch the pasta closely: Slow cookers heat differently, so start checking the rotini after 15 minutes. Pull it once it is just tender.
Shred your own cheese: Freshly shredded cheese melts smoother than pre-shredded cheese. Bagged cheese often contains starch that can turn the top grainy.
Finish with the lid on: A short covered rest melts the toppings without overcooking the pasta. It also helps the casserole slice more cleanly.
Choose the right slow cooker: A 6-quart slow cooker gives the pasta room to expand. Smaller models may cook unevenly or boil over.

FAQ

Do I need to brown the beef first?: No, if your slow cooker cooks hot and you use lean beef. Browning first gives better texture and less grease, so it is still a smart option.
Why is my pasta mushy?: It cooked too long or sat on warm too long. Add the pasta only after the beef is done, and serve soon after melting the cheese.
The sauce looks thin. How do I fix it?: Let the casserole rest uncovered for a few minutes. The pasta absorbs more liquid as it sits, and the sauce thickens fast.
Can I use pre-cooked beef?: Yes. Reduce the first cook time to about 30 minutes, just to heat the sauce and blend the flavors. Then add the pasta and continue as written.
Can I assemble this ahead?: You can measure everything ahead, but wait to add the pasta and cheese. Pasta softens quickly if it sits in liquid too long.
