Ingredients You’ll Need
- 1½ pounds lean ground beef (93% or leaner): This serves as the hearty base of your sauce. Choosing lean beef keeps the dish flavorful without being overly greasy.
- 1 small yellow onion, finely chopped: Adds sweetness and depth to the sauce. If you don’t have yellow onion, any variety will work, but yellow has the best balance of flavor.
- 3 cloves garlic, minced (or 1 tablespoon jarred minced garlic): Garlic is key for that aromatic base. Fresh is preferred, but jarred is fine in a pinch.
- 2 (28 oz) cans crushed tomatoes: The bulk of your sauce’s volume and flavor comes from these tomatoes. Look for high-quality canned tomatoes for the best results.
- 1 (14.5 oz) can tomato sauce: This adds thickness and richness to the finished sauce.
- 1 tablespoon tomato paste: Concentrates the tomato flavors and adds some sweetness.
- 1 tablespoon homemade spaghetti seasoning: This custom blend will bring all the flavors together. If you don’t have homemade, a store-bought Italian seasoning works too.
- 2 tablespoons butter (added at the end): This enriches the sauce for a velvety mouthfeel.
- Optional: fresh basil or parsley, grated parmesan, cooked pasta for serving: Fresh herbs brighten the dish, while parmesan adds an extra layer of flavor.
How to Make Best Slow Cooker Spaghetti Sauce Recipe
Combine Ingredients: In a 6-quart or larger slow cooker, add 1½ pounds of uncooked ground beef, 1 small finely chopped yellow onion, 3 minced garlic cloves, 2 cans (28 oz each) of crushed tomatoes, 1 can (14.5 oz) of tomato sauce, 1 tablespoon of tomato paste, and 1 tablespoon of homemade spaghetti seasoning. Mix gently to distribute the seasoning and break up the beef slightly. Be careful not to overmix; you want chunks of beef to remain.
Set to Cook: Cover your slow cooker and set it to cook on low for 6-8 hours or on high for 3-4 hours. The longer it cooks, the richer the flavor will become.
Finish with Butter: About 10-15 minutes before serving, stir in 2 tablespoons of butter until melted and incorporated throughout the sauce. This adds a luxurious final touch that you won’t want to skip.
Adjust Seasoning: Taste your sauce and adjust the seasoning if necessary. Sometimes a pinch of salt or pepper can make all the difference!
Serve and Garnish: Spoon over your favorite pasta, and top with grated parmesan and fresh herbs if desired. Enjoy the myriad of flavors blending together in each bite.
Storing & Reheating
To store your spaghetti sauce, let it cool completely before transferring it to an airtight container. It can sit at room temperature for about two hours before refrigerating, where it will last up to five days. For longer storage, consider freezing it in sealed bags or containers for up to three months. When you’re ready to enjoy, thaw overnight in the fridge and reheat gently on the stove until warmed through. Keep in mind that flavors may continue to develop even after cooking, so don’t be surprised if it tastes even better the next day!
Chef’s Helpful Tips
- Ensure you don’t leave the beef in large chunks; breaking it up allows for better flavor distribution.
- Avoid overcooking the garlic; add it with the onion to prevent it from burning and turning bitter.
- If you’re short on time, you can substitute ground turkey or Italian sausage for the beef for a different flavor profile.
- Experiment with adding veggies like bell peppers or mushrooms into the mix for added nutrients and flavors.
- Use a little sugar in your sauce to balance acidity if your tomatoes are particularly tart.
- This sauce is easily customizable; switch up the herbs or add a touch of red wine for a deeper flavor.
There’s something exquisite about savoring a homemade spaghetti sauce that simmers for hours, and this recipe really delivers on that front. The blend of spices, the rich tomatoes, and that final touch of butter come together perfectly to create a sauce that is not only delicious but also comforting. Whether it’s a weekday dinner or a special gathering, you’re going to want to keep this recipe in your back pocket. Feel free to mess around with the basics and make it your own—the heart of cooking lies in personal touch!
Recipe FAQs
Can I use a different type of meat?
Absolutely! Ground turkey, chicken, or even plant-based ground options work perfectly. Just adjust cooking times for the leaner meats as they might cook faster than beef.
How do I make it spicier?
If you’re after an extra kick, consider adding red pepper flakes to the sauce. Start with ½ teaspoon and increase according to your heat tolerance.
Can I make this spaghetti sauce vegan?
Definitely! Substitute the ground beef with lentils or chopped mushrooms and use vegetable broth instead of beef. Eliminate the butter or swap it for plant-based margarine.
Can I make this sauce on the stove instead?
Yes, you can! Sauté the onions and garlic in a large pot, add the remaining ingredients, and let it simmer on low for about 1-2 hours, stirring occasionally. It will be just as delicious!
