Yes — you can cook spaghetti in a crock pot, and this recipe shows you exactly how to do it without ending up with mushy noodles or watery sauce.
This Crockpot Spaghetti is rich, hearty, and incredibly easy — Italian sausage, garlic, marinara, and herbs slow cook into a deep, cozy sauce, then the pasta finishes right in the crockpot so every bite is perfectly coated. It’s a true dump-and-go dinner with big, classic spaghetti flavor.

Ready to make the easiest, coziest slow cooker spaghetti? Let’s get cooking!
✨ Before You Start
✨ Use fresh garlic — it really makes a difference! Skip the pre-minced kind and buy pre-peeled cloves if you want to save time.
✨ Break your pasta in half — this helps it coat evenly in the sauce and prevents big clumps.
✨ Mind the moisture — pasta in the slow cooker releases starch, which thickens the sauce. If it’s too tight, add broth or water. If it’s runny, use the wooden spoon or towel trick (see below!).
✨ Check your pasta early — it will be softer than stovetop pasta, closer to casserole-style. Start checking at 40 minutes to avoid mushiness.
✨ Wine or no wine — red wine adds richness, but broth works as a substitute if you’d rather skip it.
Crockpot Spaghetti Ingredients + Key Notes
Italian sausage: Use sweet or mild Italian sausage for classic flavor. You can swap in ground beef or turkey, but sausage gives the sauce its richest, most classic spaghetti flavor.
Onion: A yellow onion works best here and adds sweetness as it cooks low and slow in the sauce.
Garlic: Fresh garlic is best for the cleanest flavor. Skip the jarred kind if you can.
Marinara sauce: Use a marinara you already know you like, because it makes up most of the sauce base. A richer sauce gives you a better final result.
Red wine: This adds depth and makes the sauce taste more developed. If you prefer not to use wine, substitute beef or chicken broth.
Dried herbs: Oregano, basil, and rosemary give this sauce that slow-simmered Italian flavor. They bloom as the sauce cooks.
Sugar: Just a small amount helps balance the acidity of the tomatoes.
Spaghetti: Break it in half before adding it so it fits easily in the crockpot and cooks more evenly. Stir during cooking so the noodles don’t clump together.
🥣 How To Make Crockpot Spaghetti
Brown the sausage with the onion first, then stir in the garlic just until fragrant. Transfer everything to the slow cooker and add the marinara, wine or broth, herbs, and sugar. Cover and cook until the sauce is rich, cozy, and full of flavor.
When the sauce is ready, break the spaghetti in half and stir it into the crockpot. Make sure the noodles are well coated and mostly submerged in the sauce so they cook as evenly as possible.
Cover and cook until the pasta is tender, stirring a few times so it doesn’t clump together. If the sauce gets too thick, add a splash of broth or water. Serve hot with plenty of Parmesan and a little fresh basil or parsley on top, if you like.

⭐ Pro Tips + Variations
⭐ Managing the Moisture
If the sauce is too thick, stir in broth or water. If it’s too runny, vent the lid or drape a clean kitchen towel under the lid to absorb excess liquid. (Yes, it will stain, but it works!)
⭐ Cooking Time
Every slow cooker runs differently. Stick with 3–4 hours on high or 6–8 on low as a guideline, but always check.
⭐ Cheesy Upgrade
Stir in cream cheese, mozzarella, and parmesan for a creamier, denser spaghetti casserole vibe.
⭐ Veggie Boost
Mushrooms, zucchini, or bell peppers add heartiness, but note they may release extra moisture.
⭐ Top It Off
Finish with fresh basil, parsley, or parmesan for a restaurant-worthy touch.
What to Serve With Crock Pot Spaghetti
Fresh & Crisp Salads
Balance the richness with something fresh — a Mediterranean Salad, a fun Pizza Salad, or the classic 1905 Salad for fresh, crisp contrast.
Cozy Breads
Spaghetti night isn’t complete without bread for dipping! Bake up buttery Olive Garden Breadsticks or serve warm, golden Garlic Bread all pair beautifully.
Sweet Finishes
End the meal with something sweet and cozy. My easiest ever Chocolate Bundt Bake is the perfect finale everyone will love.
Storing + Reheating + Freezing + Make-Ahead Tips
Storing
Cool leftovers completely, then refrigerate in an airtight container for up to 4 days.
Reheating
Warm gently on the stovetop over medium heat, adding a splash of broth or water to loosen the sauce. For larger portions, cover with foil and reheat in a 350°F oven for 15–20 minutes.
Freezing
Freeze cooled spaghetti in freezer-safe containers for up to 2 months. Thaw overnight in the fridge before reheating.
Make-Ahead
The sauce can be made a day or two in advance (or frozen) and reheated in the crockpot. Wait to add the pasta until the day you serve.

Frequently Asked Questions
◆ Can I use ground beef or turkey instead of sausage?
Yes! Just season well since leaner meats have a milder flavor.
◆ Do I have to use wine?
Nope — beef or chicken broth works perfectly. Water in a pinch, though it may slightly dilute the flavor.
◆ Why is my pasta mushy?
Slow cooker pasta cooks softer than stovetop. Start checking at 40 minutes, stir occasionally, and don’t let it go too long.
◆ Can I add veggies?
Definitely! Mushrooms, bell peppers, or zucchini are tasty additions. Just keep in mind they’ll release liquid into the sauce.
◆ Can I make this cheesy?
Absolutely — stir in cream cheese for creaminess and top with mozzarella and parmesan before serving.

Crock Pot Spaghetti
Ingredients
- 1 tablespoon olive oil
- 1 pound sweet Italian sausage, casing removed
- 1 medium yellow onion, chopped
- 1 heaping tablespoon garlic, minced
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 2 teaspoons dried oregano
- 2 teaspoons dried basil
- 1 teaspoon dried rosemary
- 1/4 teaspoon granulated sugar
- 2 (26-ounce) jars marinara sauce
- 1 cup red wine
- 2 1/2 cups water
- 1 pound spaghetti uncooked
Instructions
- In a large skillet, heat the olive oil (1 tablespoon) until it shimmers. Add Italian sausage (1 pound), onion, and garlic, and cook over medium heat until sausage is cooked through. Drain off excess fat. Pour the drained sausage mixture into a large crock pot.
- Add salt (1 teaspoon), pepper (1/2 teaspoon), oregano (2 teaspoons), basil (2 teaspoons), rosemary (1 teaspoon), sugar (1/4 teaspoon), 2 jars of marinara sauce, red wine (1 cup), and water (2 1/2 cups) to the crockpot and stir together. Cook on high for 3-4 hours or low for 6-8 hours.
- Cover and turn the crockpot on high for the last hour add spaghetti (1 pound). Break noodles, as needed to fit into crockpot. Stir the noodles well into the sauce so they're coated with the sauce. Check pasta after 45 minutes to see if the spaghetti is done. Add more water as needed to loosen the sauce.

Notes
- Managing the Moisture- If the sauce is too tight, simply add a little broth or water and stir. However, decreasing moisture in a runny sauce can be a little more tricky. You can prop open the top with a wooden spoon or remove it entirely.
- You can also drape a clean kitchen towel across the pot under the lid. Beware you’ll probably stain your towel, but it’s quite effective at soaking up excess moisture!
- Cooking Time – Look, every crock pot is different. Period. There’s no magic cooking time I can tell you. What’s in the recipe is a general guideline: 3-4 hours on high or 6-8 hours on low. The exact cooking time may (will) vary based on your cooker.

So so good! I usually add ground beef into mine but switching it to Italian sausage is way better !!
Recipe looks great….but…any non-alcoholic sub for red wine?
Hi, Ginger. You can substitute chicken or beef broth. You can use water in a pinch, but it might dilute the flavor slightly.
Hi Ginger. You can just omit it. 🙂
Just Brilliant!!! I have a heat and sear slow-cooker so only one pan!!
Ooooh that’s awesome, Jean! Enjoy! 😀
Hi Kathleen,
Just a quick note to say I usually put my water to be added into my marinara jar, shake and that way you get all of the sauce from the jar. Love your site.
