“My all time favourite spaghetti sauce!! The splash of wine gives it a nice edge.”
– Kevin
When it comes to pasta sauce, your first thought might be to grab a few jars from the grocery store. While that’s certainly convenient, you can just as easily whip up a delicious, homemade sauce right in your own kitchen and also have plenty of leftovers. This is my mom’s recipe that I’ve adapted for the slow cooker. I think you’ll love it!
Recipe Ingredients
Ground Beef – Cooked and drained for a hearty base.
Canned Tomatoes – Crushed, diced (undrained), and tomato paste for rich texture and flavor.
Onion & Garlic – Diced onion and fresh minced garlic for depth and aroma.
Seasonings – A blend of brown sugar, oregano, basil, salt, pepper, and red pepper flakes for the perfect balance of sweet and savory.
How to Make Slow Cooker Spaghetti Sauce
- Cook the beef in a pan, then remove any excess grease.
- Combine all the ingredients in the Crockpot.
- Set the lid on and let simmer away. Remember, the longer this cooks, the better it gets.
Tips & Variations
- Meat Swaps: You can substitute one pound of Italian Sausage for the ground beef in this recipe. You can also use ground turkey or ground chicken or 2 lbs of frozen meatballs.
- Adding Wine: Add a half cup of red wine at the beginning of the recipe if you would like a red wine flavored sauce. I like to use red blend when I’m cooking (and for drinking).
- Veggies: Add additional vegetables such as diced carrots, celery, or mushrooms.
How to Serve:
Here is how I serve this spaghetti sauce from the slow cooker to my family and guests:
- Spoon this homemade spaghetti sauce over your favorite noodles—such as spaghetti, angel hair, or bucatini. Try zucchini noodles if you’re keeping it low-carb.
- You can also use this sauce for lasagna or try it in a ravioli lasagna for a fun and different twist.
- Serve it up with garlic bread, breadsticks, or any crusty bread you love to round out the meal.
- Reader Suggestion: Stir in some butter just before serving.
How to Store Extra Spaghetti Sauce:
Place extras in the fridge for up to four days. Or for more extended storage, spoon into small portions and freeze for up to three months. Great for last-minute budget meals.
