Cheesy Spaghetti Sloppy Joes blend nostalgia and comfort into one easy family meal by uniting hearty ground beef, saucy spaghetti, and plenty of gooey mozzarella right inside a toasted bun. This is hands-down my go-to crowd-pleaser when everyone wants something filling but I am short on time or groceries.
The first time I served this mashup was after a late soccer practice when everyone was starving. Every plate was clean and now it is a regular request.
Ingredients
- Lean ground beef: for flavor and protein Look for beef with less fat so your sandwich stays juicy not greasy
- Yellow onion: diced for sweetness and depth Fresh onions are best for real character
- Water: keeps the spaghetti moist and gives noodles a creamy texture as they cook
- Spaghetti noodles: broken into quarters so they fit perfectly on the bun I prefer classic wheat for bite
- Classic Sweet Basil Marinara sauce: gives the signature Italian spin Pick one with bright tomato flavor and visible herbs
- Salt and pepper: for basic seasoning Go with fresh cracked pepper and kosher salt for best impact
- Onion powder and garlic powder: boost the savory notes Essential for building a true Sloppy Joe taste
- Large hamburger buns: to cradle all the goodness Seek out bakery style buns with a soft crumb and hearty enough to hold the filling
- Garlic margarine or butter: takes the toasted buns over the top Brush generously for max flavor
- Mozzarella cheese: shredded for melt Pull cheese by hand if you like extra stretchiness
Step-by-Step Instructions
- Brown the Beef and Onions:
- Start by heating a large saute pan over medium high. Add lean ground beef and a dab of butter or margarine. As it cooks, break it apart and add your diced yellow onions. Stir occasionally and let it brown fully for eight to ten minutes until all beef is no longer pink and onions look translucent. This layering develops the base flavor.
- Drain and Add Liquids:
- Once cooked, carefully drain any grease from the pan so only the beef and onions remain. Now pour in two cups of water. The water will help the spaghetti cook right inside the pan which means less mess and more flavor.
- Add Spaghetti Noodles:
- Break spaghetti into pieces about two inches long and sprinkle them into the pan. Stir gently so the noodles are spread out and coated. Put a lid on the pan without lowering the heat.
- Steam and Stir:
- Let the noodles cook in this steam bath for four minutes. Then remove the lid and stir everything so no strands stick. This step ensures tender spaghetti every time.
- Sauce It:
- Pour your sweet basil marinara sauce into the skillet. Stir until every noodle and piece of beef is bathed in sauce and there are no dry spots.
- Season the Mix:
- Add in salt pepper onion powder and garlic powder. Stir again to incorporate. Drop the heat to low so your filling stays hot but does not scorch the sauce.
- Toast Buns:
- Lay the hamburger buns in a single layer on a baking sheet. Slather garlic margarine across each cut side. Bake at four hundred degrees until edges start turning golden and you can smell the garlic about four to six minutes.
- Add Cheese:
- With heat on low add the shredded mozzarella right to your spaghetti mixture. Stir and fold until the cheese melts smoothly and clings to everything.
- Build and Serve:
- Spoon generous scoops of cheesy spaghetti mix onto toasted buns and enjoy immediately while gooey and warm.

Mozzarella is forever a favorite of mine Because it melts into spectacular long pulls and the mild flavor lets the tangy tomato sauce shine My kids love to compete over who can get the cheesiest bite right off the spoon or from their sandwich
Storage Tips
Leftover filling keeps well in a covered container for up to three days in the fridge Warm in a pan with a splash of water or more sauce to revive Creamy cheese will get gooey again Buns can be toasted up fresh with more garlic butter right before serving
Ingredient Substitutions
If you are out of beef ground turkey or chicken works great For noodles substitute short pasta shapes like elbows or shells. Use any marinara style sauce or even homemade if you want. Vegan cheese and plant based butter keep this dairy free without sacrificing comfort
Serving Suggestions
I always serve these with a crisp green salad or steamed broccoli for balance A big fruit salad is a great side for kids. Bring plates right to the table with extra sauce for dipping for a fun meal All ages will love

Cultural Context

Recipe FAQs

Yes, provolone, Monterey Jack, or cheddar also work beautifully in this dish, depending on your flavor preference.
- → Is it possible to prepare ahead?
You can cook the beef and spaghetti mixture ahead and reheat just before assembling. Toast the buns fresh for best texture.

Ground turkey is a suitable alternative and will create a lighter dish while still retaining plenty of flavor.
