Key Ingredients & Substitutions
Spaghetti: A classic choice for this dish! If you’re gluten-free or looking for a healthier option, consider using zucchini noodles, whole wheat pasta, or gluten-free pasta. Each variation offers a unique twist!
Meatballs: You can use frozen or fresh meatballs, but I love making homemade ones for a personal touch. If you’re short on time, frozen meatballs work well. For an alternative, try turkey or veggie meatballs for a lighter meal.
Marinara Sauce: While store-bought is convenient, making homemade marinara with fresh tomatoes, herbs, and garlic boosts flavor. If you’re short on ingredients, you could substitute with pesto for a different taste!
Parmesan Cheese: Grated parmesan adds a salty touch. If you’re dairy-free, nutritional yeast provides a cheesy flavor without the dairy. You can also use pecorino Romano for a sharper taste.
How Do I Cook Meatballs Perfectly in the Crockpot?
Cooking meatballs in the crockpot is easy, but achieving the right texture is key. Whether using frozen or fresh, follow these steps for the best results:
- If using raw meatballs, browning them in a skillet first adds depth of flavor. Just cook until they’re golden brown, then transfer them to the crockpot.
- Place the meatballs in the sauce, making sure they are fully submerged, which keeps them moist while cooking.
- Check if they reach an internal temperature of 165°F (75°C) when cooking time is up. This ensures they are cooked through.
Letting them simmer for a longer time can enhance their flavor while still keeping them tender. Enjoy your flavorful meatballs!

How Much Time Will You Need?
This recipe will take about 10 minutes for preparation and then a cooking time of 6-7 hours on low or 3-4 hours on high. It’s perfect for busy days when you want a delicious meal without any fuss!
Step-by-Step Instructions:
1. Prepare the Sauce Base:
Start by adding the marinara sauce to your crockpot. Then, stir in the finely chopped onion, minced garlic, Italian seasoning, salt, black pepper, and red pepper flakes if you’re feeling adventurous with some heat. This hearty mixture is the foundation of your flavorful dish!
2. Add Meatballs:
Now it’s time for the meatballs! Simply place the meatballs into the sauce, making sure they are well-coated. If you’d like a richer flavor, you can brown the meatballs in a skillet with a little olive oil before adding them to the crockpot, but this is totally optional.
3. Cook Meatballs and Sauce:
Cover the crockpot and set it to low for 6-7 hours or high for 3-4 hours. Let the magic happen as the meatballs cook and the flavors meld together. Don’t forget to check if they’re fully cooked; the internal temperature should reach 165°F (75°C).
4. Cook Spaghetti:
About 20 minutes before your meatballs are done, boil water in a separate pot and cook the spaghetti according to the package instructions until it’s al dente. Once done, drain it well and set aside.
5. Combine and Serve:
After everything is cooked, serve the savory meatballs and sauce generously over your spaghetti. Don’t hold back on the Parmesan cheese—sprinkle it on top and finish with a sprinkle of chopped fresh parsley for that vibrant touch!
6. Optional Enhancements:
For an extra touch of flavor, you might want to drizzle a little olive oil on top or add some fresh basil leaves. It adds a delightful aroma to your lovely dish.
Now grab a fork and enjoy your hearty plate of crockpot spaghetti and meatballs. It’s comfort food at its finest!
Can I Use Frozen Meatballs in This Recipe?
Absolutely! Frozen meatballs work great and save time. Just toss them directly into the crockpot without thawing. They’ll cook perfectly in the sauce!
How Do I Store Leftovers?
Leftovers can be stored in an airtight container in the fridge for up to 3 days. For best results, separate the spaghetti and meatballs to prevent the noodles from getting soggy. Reheat on the stove or microwave before enjoying again.
Can I Make This Recipe Ahead of Time?
Yes, you can prepare everything in the crockpot the night before, refrigerate it, and then just plug it in on the day you want to cook. This makes it super convenient for busy days!
