There are certain dinners that just feel like a hug in a bowl, and spaghetti is right at the top of that list. But let’s be honest — standing over a pot of boiling water, stirring sauce so it doesn’t stick, and managing multiple burners after a long day isn’t always in the cards. That’s where this crock pot spaghetti comes in. You basically dump everything into the slow cooker, walk away, and come back to a fully cooked, deeply flavorful pasta dinner that tastes like you worked on it for hours.
Now, I know what you might be thinking: pasta in a slow cooker? Won’t it turn into mush? The trick is to add the spaghetti during the last part of cooking so it absorbs all that delicious sauce without getting soggy. The result is a one-pot meal where the noodles cook right in the marinara, soaking up every bit of flavor from the seasoned ground beef and Italian herbs.
If you’re feeding a crowd, meal prepping for the week, or just want dinner to handle itself while you tackle everything else on your list, this recipe is about to become a heavy hitter in your rotation.
What to serve with it:
Spaghetti is practically a complete meal on its own, but a few simple sides round it out beautifully. A crisp green salad with a tangy vinaigrette cuts through the richness of the sauce. Garlic bread or a crusty baguette is never a bad idea — perfect for sopping up any leftover sauce in the bowl. For vegetables, roasted broccoli, sautéed zucchini, or steamed green beans add color and nutrition without much effort.
If you’re meal prepping, portion the spaghetti into containers with a side of roasted vegetables or a small salad. This reheats beautifully in the microwave, though you may want to add a splash of water or broth to loosen the sauce.
Crock Pot Spaghetti
Servings: 6–8 servings
Ingredients
· 1 pound lean ground beef (or ground turkey)
· 1/2 cup diced yellow onion
· 3 cloves garlic, minced
· 1 teaspoon salt
· 1/2 teaspoon black pepper
· 1 teaspoon dried oregano
· 1 teaspoon dried basil
· 24 ounces marinara sauce (about 3 cups)
· 15 ounces diced tomatoes, undrained
· 4 cups low-sodium beef broth or water
· 12 ounces dried spaghetti, broken in half
· 1/2 cup grated Parmesan cheese, plus more for serving
· Fresh basil or parsley, chopped (for garnish)
Directions
1. In a skillet over medium-high heat, cook the ground beef and onion until the beef is browned and the onion is softened, about 5–7 minutes. Drain any excess fat.
2. Add the minced garlic, salt, pepper, oregano, and basil. Cook for 1 minute until fragrant.
3. Transfer the beef mixture to a 6-quart slow cooker. Add the marinara sauce, diced tomatoes (with their juices), and beef broth. Stir to combine.
4. Cover and cook on LOW for 4–5 hours or on HIGH for 2–3 hours.
5. Break the spaghetti noodles in half and add them to the slow cooker. Stir well to submerge the noodles in the liquid as much as possible.
6. Cover and cook on HIGH for 30–45 minutes, stirring once halfway through, until the spaghetti is tender and has absorbed most of the liquid.
7. Stir in the 1/2 cup of Parmesan cheese until melted and incorporated.
8. Let the spaghetti rest for 5–10 minutes before serving — the sauce will continue to thicken.
9. Garnish with fresh basil or parsley and additional Parmesan cheese. Serve warm.
Variations & Tips
· Lighter version: Use ground turkey or ground chicken instead of beef, and choose a low-sugar marinara sauce. You can also use whole wheat spaghetti for more fiber.
· Vegetarian: Omit the meat and add 8 ounces of sliced mushrooms or 1 cup of cooked lentils along with the sauce. Use vegetable broth instead of beef broth.
· Spicy: Add 1/2 teaspoon red pepper flakes or use a spicy arrabbiata sauce in place of regular marinara.
· Extra vegetables: Stir in 1 cup of finely chopped carrots, bell peppers, or zucchini along with the onion. You can also add a handful of fresh spinach at the end, stirring until wilted.
· Cheesy: Stir in 1/2 cup of shredded mozzarella along with the Parmesan, or top each serving with fresh mozzarella pearls.
· No pre-cooking shortcut: You can skip browning the beef and add it raw to the slow cooker, but browning first adds a much deeper flavor. If skipping, crumble the raw beef into the sauce and cook on LOW for 6–7 hours, breaking it up with a spoon occasionally.
· Make it creamy: Stir in 1/4 cup of heavy cream or cream cheese at the end for a creamy tomato sauce.
· Leftovers: Store in an airtight container in the fridge for up to 4 days. Add a splash of water or broth when reheating to bring back the saucy consistency.
