Spaghetti and Meatballs.

There’s something deeply comforting about a pot of warm tomato sauce and perfectly seasoned meatballs simmering together. This Spaghetti and Meatballs recipe is cozy, approachable, and built on straightforward pantry-friendly ingredients. Inspired by the homey, no-fuss sensibility of favorite food blogs, the dish balances savory beef, tangy Parmesan, and a bright hit of parsley. It’s the kind of meal that fills the kitchen with tempting aromas and brings people to the table with empty plates and big smiles.

Why this Spaghetti and Meatballs works

It’s all in the texture and timing. The meatballs here use 1 pound lean ground sirloin combined with bread crumbs, grated Parmesan, chopped parsley, and a single egg to bind — enough moisture to keep them tender without being greasy. A touch of dried oregano and crushed red pepper flakes gives subtle warmth and aromatic lift, while kosher salt and black pepper keep flavor balanced. Browning the meatballs in 2 tablespoons olive oil creates a caramelized crust that holds up when they finish cooking in a jar of marinara sauce, which lets the flavors marry without drying the meat. Serve over whole wheat pasta or spaghetti squash for a wholesome finish, and top with 1/3 cup shredded mozzarella for melty, irresistible cheese.

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

Prep notes

Gather everything before you begin. Measuring the bread crumbs and cheese ahead makes mixing faster and more even. If you choose spaghetti squash, plan for a slightly longer cook time; it becomes tender-roasted strands that pair beautifully with tomato sauce. If you prefer whole wheat pasta, choose a shape that holds sauce well — traditional spaghetti is perfect, but short pasta like penne or fusilli works, too.

Step-by-step directions

1. Preheat and prepare. If you’re using spaghetti squash, preheat the oven to 400°F, halve and seed the squash, brush with a little oil, and roast cut-side down on a lined baking sheet while you make the meatballs. If you’re using whole wheat pasta, bring a large pot of salted water to a boil but don’t cook the pasta yet — it will finish while the meatballs simmer.
2. Make the meatball mixture. 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, a generous pinch of kosher salt, and a few grinds of black pepper. Crack 1 egg into the bowl and mix gently with your hands or a spoon until ingredients are just combined; do not overwork the meat or the meatballs may become dense.
3. Shape the meatballs. Using slightly moistened hands, form the mixture into even meatballs about the size of golf balls. You should end up with roughly 12–16 meatballs depending on exact size. Place them on a plate or baking sheet while you heat the pan.
4. Brown the meatballs. Heat 2 tablespoons olive oil in a large, heavy-bottomed skillet over medium-high heat. When the oil shimmers, add the meatballs in a single layer without crowding the pan; work in batches if necessary. Brown the meatballs on all sides, turning carefully with tongs or a spatula, about 6–8 minutes total. You want a deep golden crust but not to cook them through entirely.
5. Add the sauce and finish cooking. Once the meatballs are browned, pour 1 jar marinara sauce into the skillet, gently nestling the meatballs into the sauce. Reduce the heat to low, cover, and let simmer for 12–15 minutes. This finishes cooking the meatballs through and allows them to soak up the tomato flavor. Uncover for the last few minutes if the sauce looks too thin to let it thicken slightly.
6. Prepare the pasta or squash. If you’re cooking whole wheat pasta, add it to the boiling water and cook according to package instructions for al dente. Reserve a ladleful of pasta cooking water before draining; you can use a splash to loosen the sauce if needed. If you roasted spaghetti squash, use a fork to scrape the flesh into strands once it’s tender and cool enough to handle.
7. Combine and melt the cheese. When the meatballs are fully cooked and the sauce is hot, sprinkle 1/3 cup shredded mozzarella over the top. Cover the skillet briefly for 1–2 minutes off the heat to let the cheese melt, or transfer to a warm oven for a couple of minutes if you prefer a bubbling top.
8. Serve. Plate the cooked whole wheat pasta or a nest of spaghetti squash and spoon several meatballs and sauce over each serving. Finish with an additional sprinkle of chopped parsley and a grind of black pepper if desired. If your sauce needs thinning, stir in a tablespoon or two of the reserved pasta water to reach your desired consistency.

Troubleshooting and tips

Meatballs too dense? Don’t overmix the meat mixture; combine until just blended. If the mixture seems dry, add a teaspoon of water or a splash of milk to loosen it slightly. Browning in batches keeps the pan hot enough to sear rather than steam the meatballs — crowded meatballs will release moisture and won’t develop a crust.

Want lighter meatballs? You can substitute part of the ground sirloin with ground turkey or a lean lamb blend, keeping the same 1 pound total and leaving all other ingredient amounts unchanged. For extra flavor, gently sauté a small diced onion and two minced garlic cloves in the olive oil, cool, and add to the meatball mixture before shaping — though this is optional and will change the texture slightly.

Make-ahead and storage

Meatballs keep well. After simmering, cool completely and store meatballs and sauce together in an airtight container in the refrigerator for up to 4 days. Reheat gently on the stove over low heat until warmed through. For longer storage, freeze assembled meatballs with sauce in single-portion containers for up to 3 months; thaw overnight in the fridge before reheating.

Variations to try

• Herbed and cheesy: Fold an extra tablespoon of chopped parsley or basil into the meatball mix and increase the Parmesan to 1/3 cup for more cheesy depth.
• Spicy tomato: Add another pinch of crushed red pepper flakes to the sauce or stir in a teaspoon of smoked paprika for smoky warmth.
• Veggie-packed: Serve the sauce over spaghetti squash and toss in roasted vegetables like bell peppers and zucchini to boost fiber and color.

Serving suggestions

Light, bright sides keep this dish balanced. A crisp green salad with a lemony vinaigrette, simple sautéed greens, or a tray of roasted root vegetables pairs well. Finish the plates with extra grated Parmesan and a scattering of chopped parsley for freshness.
