My coworker shared this secret for game day snacking. Just 3 ingredients. A gooey, savory mouthful that tastes better than takeout.

This little low carb 3-ingredient meatball bake is the kind of thing we used to throw together on Sunday afternoons when the game was on and the house was full of hungry people. A coworker of mine at the school cafeteria actually tipped me off to this shortcut years ago: frozen meatballs, a good jar of sauce, and plenty of mozzarella. That’s it. It comes out of the oven bubbling and browned around the edges, smelling like a cozy Italian restaurant, but it’s simple enough to make during halftime. No breadcrumbs, no pasta, and no fuss—just a gooey, savory mouthful that feels like takeout, only warmer and more homemade.

Serve these meatball bakes right out of the casserole dish with a big spoon so everyone can help themselves. For a low carb spread, I like to set them alongside a crisp green salad with a tangy vinaigrette and a tray of raw veggies. If you’re not counting carbs too closely, they’re wonderful spooned over roasted zucchini, spaghetti squash, or even a slice of toasted garlic bread. A cold beer or a pitcher of iced tea fits right in on game day, and a bowl of extra warmed sauce on the side lets folks make things as saucy as they like.

Servings: 4

1 24-ounce jar low-sugar marinara or pizza sauce

Preheat your oven to 375°F (190°C). Lightly grease a medium ceramic casserole dish (about 9x9 inches or similar size).

Pour about 1 cup of the marinara or pizza sauce into the bottom of the casserole dish and spread it into an even layer.

Arrange the frozen fully cooked beef meatballs in a single, snug layer over the sauce. It’s fine if they touch; just try to keep them in one even layer so they bake evenly.

Spoon the remaining sauce over the tops of the meatballs, making sure each one gets at least a little sauce so they stay moist and soak up flavor.

Sprinkle the shredded mozzarella cheese evenly over the sauced meatballs, covering them from edge to edge. This is what gives you that gooey, browned top that feels like takeout.

Place the casserole dish on the middle rack of the preheated oven and bake for 25–30 minutes, or until the sauce is bubbling, the cheese is fully melted, and the edges are golden brown.

If you like a deeper brown top, switch the oven to broil for 1–3 minutes at the end, watching very closely so the cheese browns without burning.

Remove the dish from the oven and let the meatball bake rest for about 5 minutes so the cheese can settle slightly. Serve hot, scooping out meatballs, sauce, and plenty of that gooey melted cheese.

If you’d like a little extra flavor without adding more ingredients, choose a marinara or pizza sauce that’s labeled spicy or garlic-heavy, or pick Italian-style seasoned meatballs. To stretch the dish for a bigger crowd, use a larger casserole and add another half bag of meatballs and a bit more cheese, keeping the same simple 3-ingredient formula. For individual portions, divide the meatballs, sauce, and cheese into small ramekins and bake them on a sheet tray for personal mini bakes. If you prefer turkey or chicken, swap in frozen fully cooked poultry meatballs, but keep an eye on them so they don’t dry out—pull the dish from the oven as soon as the cheese is bubbling and lightly browned. You can also play with texture by baking a few minutes longer for extra-crispy cheese around the edges, which is especially nice if you’re skipping bread. Leftovers reheat well in a low oven or microwave; just cover loosely so the cheese doesn’t toughen.
