What’s to Love About This Recipe
“We’ve made this pasta sauce MANY times. The meat combo (using both ground beef and ground pork) adds such flavor. Great recipe!” – Janny
Here’s why I think you’re going to enjoy this slow cooker spaghetti sauce, too…
- Hearty, Nutritious Dinner: Serve over whole grain pasta, zoodles, spaghetti squash, or even quinoa.
- Slow Cooks All Day: Similar to our Crock Pot Taco Soup and Creamy Sausage and Tortellini Soup, just brown the meat and toss everything in the crock pot.
- Only 6 Main Ingredients
- Freezer-Friendly: Just double and freeze the second batch for another meal.
- Gluten-Free and Dairy-Free
- Leftovers Are Great: Serve it up with some Texas Toast and Roasted Broccoli for a super easy meal.
Ingredients
As we also mention in our Crockpot Tortellini Soup with Sausage recipe, don’t be fooled into thinking this is a boring sauce just because it’s simple. Check out the heavy-hitting lineup of complex flavors of these 6 ingredients!
Ingredient Notes
- Lean Ground Beef – I use grass-fed, organic lean ground beef, but you can easily sub ground turkey or ground chicken.
- Ground Italian Sausage – You can use mild or spicy Italian pork sausage, but make sure it’s ground (not pre-cooked in a link). You can also substitute ground turkey or chicken sausage here.
- Marinara Sauce – Be sure to read the ingredients and try to avoid “natural flavors”, a lot of added sugar, and other weird ingredients you’re not familiar with. I personally love Newman’s Own Marinara Sauce. Or, try making your own with our Slow Cooker Marinara Sauce recipe. It’s cheap, budget-friendly, freezable, and amazing!

How Long to Cook Spaghetti Sauce in Crockpot
This is an all-day slow cooker recipe.
You’ll need to do about 20 minutes of work ahead of time to build flavor, including chopping and sautéing the aromatics (onion and garlic) and browning the meat.
Then, dump all the ingredients into the crockpot and let them gently simmer away all day long–about 8 hours–on LOW. Your home will smell amazing by dinner time!
How to Freeze Spaghetti Sauce
This is one meal that you’ll definitely want to double, so you can freeze a batch for later.
How to Freeze For Later:
Option 1 (Uncooked): Saute the onion/garlic and then brown the meat with red pepper flakes on the stovetop. Let the meat mixture cool, then transfer it to a gallon-size freezer bag or container and pour in the marinara. Seal, gently toss to combine, and freeze flat.
Option 2 (Fully Cooked): Let the sauce fully cool. Then, freeze in a gallon-size freezer bag or container.
How to Prepare From Frozen:
Thaw using one of our safe methods.
Option 1 (Uncooked): Transfer the sauce to the slow cooker and cook on LOW for 6-8 hours.
Option 2 (Fully Cooked): Warm on the stovetop or in the crockpot over low heat untiled warmed through, stirring occasionally.
Freezing Tip: It’s helpful to freeze the bag of sauce on a rimmed baking sheet to prevent spills and to freeze until it’s flat. Once it’s frozen solid, remove the pan and the meal will stack easily in the freezer.
Make it in the Instant Pot
You can cook the entire meal, including the sauce and spaghetti(!!), in your Instant Pot.

Instructions
Make It Now:
1. In a large skillet, heat the oil over medium-high heat until shimmery. Add the onion and cook, stirring, until soft, 4 to 5 minutes, stirring in the garlic the last 30 to 60 seconds of cooking. Add the ground beef and sausage and cook, breaking up the meat as it cooks, until browned, 5 to 7 minutes, seasoning lightly with salt, pepper, and the red pepper flakes while it cooks. Drain the grease from the pan.
2. Transfer the meat mixture to the slow cooker and stir in the marinara sauce. Cover and cook on Low for 6 to 8 hours. If the edges start to burn a little, just give it a stir.
3. Serve the sauce over whole-grain pasta, zoodles, spaghetti squash, or quinoa, topped with Parmesan, if desired.
How to Freeze For Later:
Option 1 (Uncooked): Follow Step 1. Let the meat mixture completely cool, then transfer it to a gallon-size freezer bag and pour in the marinara sauce. Seal, gently toss to combine, and freeze.
Option 2 (Fully Cooked): Follow Steps 1 and 2. Let the sauce fully cool. Then, freeze in a gallon-size freezer bag or container.
How to Prepare From Frozen:
Thaw using one of our safe methods. (Never place frozen food in the slow cooker! It’s unsafe according to the USDA.)
Option 1 (Uncooked): Transfer the sauce to the slow cooker and cook on LOW for 6-8 hours.
Option 2 (Fully Cooked): Warm on the stovetop, in the crockpot, or in the microwave untiled warmed through, stirring occasionally.
Notes/Tips
- Dairy-Free Version: The sauce is dairy-free, but leave off the Parmesan cheese when serving.
- Gluten-Free Version: The sauce is gluten-free, but serve over GF pasta, zoodles, spaghetti squash (my favorite!), or quinoa.
- Tip for Buying Marinara Sauce: We recommend buying an organic or all-natural brand of marinara sauce to avoid additives and preservatives. My favorites are Newman’s Own Marinara Sauce or Rao’s brand. Alternatively, you can make your own delicious sauce using this recipe.
- Sometimes when I make this, I toss in about 1 teaspoon of crushed oregano or Italian seasoning when cooking the meat to add extra flavor.
- Toss in some chopped spinach, too, and no one even knows.
A really great sauce recipe.
One of the best I have tried.
Glad you enjoyed this. Thanks for leaving a review!
Can you make this and can it?
I haven’t tested doing that, but maybe someone else here has?
So easy and definitely better than store bought
Hi Tracie! Thanks for leaving a review. 🙂
We’ve made this pasta sauce MANY times. The meat combo (using both ground beef and ground pork) adds such flavor. We even chopped up and tossed in a couple of leftover Italian sausages last time we made it. Great recipe!
