Spaghetti and Meatballs.

I’ve always loved a cozy, saucy plate that brings people together, and this Spaghetti and Meatballs recipe does exactly that. It’s simple, comforting, and made with ingredients you likely already have on hand. The meatballs are tender and seasoned just right, the sauce is rich and familiar, and you can serve it over whole wheat pasta or a lighter bed of spaghetti squash. Below, you’ll find everything from the ingredient list to clear, step-by-step directions, plus tips for perfect texture and make-ahead strategies.

Why this version works

This Spaghetti and Meatballs keeps things straightforward without skimping on flavor. Lean ground sirloin keeps the meatballs tender but not greasy. A touch of Parmesan and fresh parsley builds savory depth, while dried oregano and crushed red pepper flakes add an Italian-inspired lift. Using bread crumbs and a single egg helps the meatballs hold together, and finishing with a sprinkle of shredded mozzarella gives that melty, irresistible top layer.

Ingredients

• 1 pound lean ground sirloin
• 3/4 cup bread crumbs
• 1/4 cup grated parmesan cheese
• 1/4 cup chopped parsley
• 1 teaspoon dried oregano
• pinch of crushed red pepper flakes
• kosher salt and pepper
• 2 tablespoons olive oil
• 1 egg
• 1 jar marinara sauce
• 1/3 cup mozzarella shredded
• whole wheat pasta or spaghetti squash for serving

Make-ahead notes

You can mix the meatball mixture and shape the balls a day in advance, then store them covered in the fridge. If you want to freeze, flash-freeze the shaped meatballs and transfer to a freezer-safe container; thaw overnight before cooking. The sauce can be made a day ahead as well for even better flavor.

Step-by-step directions

1. Preheat a skillet over medium heat and add 2 tablespoons olive oil so it warms while you prep the meatballs.
2. In a large bowl, combine 1 pound lean ground sirloin, 3/4 cup bread crumbs, 1/4 cup grated parmesan cheese, 1/4 cup chopped parsley, 1 teaspoon dried oregano, a pinch of crushed red pepper flakes, kosher salt and pepper to taste, and 1 egg. Use your hands or a fork to mix just until everything is evenly combined; avoid overworking the mixture so the meatballs stay tender.
3. Form the mixture into evenly sized meatballs—about 1 to 1.5 inches in diameter—so they cook uniformly. This recipe should yield roughly 16–20 meatballs depending on the size you choose.
4. When the skillet and oil are hot, add the meatballs in a single layer without crowding. Cook for 3–4 minutes on the first side until browned, then gently roll to brown the other sides. You’re aiming for a golden crust, not to cook them through completely.
5. Once browned, pour 1 jar marinara sauce into the skillet with the meatballs or transfer the meatballs to a saucepan and pour the sauce over them. Reduce the heat to low, cover, and simmer for 12–15 minutes, turning the meatballs once halfway through so they soak up the sauce flavor and finish cooking through. The internal temperature should reach 160°F (71°C) for fully cooked beef.
6. Meanwhile, prepare your chosen base: cook whole wheat pasta according to package directions until al dente, or roast and shred a spaghetti squash. Reserve a cup of pasta cooking water if using pasta; a splash can loosen the sauce if needed.
7. When the meatballs are cooked through, sprinkle 1/3 cup mozzarella shredded over the saucy meatballs, cover the pan briefly until the cheese melts—about 1–2 minutes.
8. Serve the meatballs and sauce over the cooked whole wheat pasta or spaghetti squash. Finish with extra chopped parsley or a grind of pepper if you like.

Tips for success

• Measure the breadcrumbs by lightly spooning them into the cup so the texture isn’t too dense—this helps the meatballs stay tender.
• If the meatball mixture feels too wet, add a little more bread crumbs; if too dry, add a splash of water or an extra beaten egg white.
• Browning the meatballs first gives them a better texture and richer flavor than simmering alone.
• Simmer gently—vigorous boiling can break the meatballs apart.
• For a lighter finish, use low-moisture mozzarella and don’t overheat after adding it, so it melts evenly without becoming stringy.

Variations

• Spicy: Add extra crushed red pepper flakes to the meatball mix and stir a pinch into the sauce.
• Herby: Fold in 1–2 tablespoons of chopped fresh basil or swap half the parsley for fresh basil.
• Cheesy center: Press a small cube of mozzarella into the center of each meatball before sealing and cooking for gooey insides.
• Low-carb: Serve over spaghetti squash instead of whole wheat pasta for a lighter meal.

Serving suggestions

A crisp green salad and warm garlic bread are classic companions. For a lighter plate, pair with roasted vegetables or a lemony arugula salad. Leftovers make excellent sandwiches—pile meatballs and sauce into toasted rolls and finish with extra shredded mozzarella.

Storing and reheating

Refrigerate cooled leftovers in an airtight container for up to 3 days. To reheat, gently warm the meatballs and sauce on the stove over low heat until just simmering, or heat individual portions in the microwave in 30-second bursts. If the sauce has thickened, stir in a splash of water or reserved pasta cooking water to loosen it.

Final thoughts

This Spaghetti and Meatballs recipe is reliable, approachable, and crowd-pleasing. It balances straightforward ingredients with comforting technique: quick browning, slow simmering, and a finishing touch of mozzarella. Whether you’re feeding a family, prepping for meal night, or craving something satisfying after a long day, this classic hits the spot every time.
