Ground Beef: Slow Cooker Spaghetti Sauce

This savory and satisfying slow cooker spaghetti sauce with ground beef comes together easily with a handful of pantry ingredients. It cooks in a crockpot all day for rich deep flavor and makes for the just right weeknight or meal-prep recipe.
One of our all time favorite foods is meat sauce or bolognese. It is on our weekly rotation, which is why we have many a recipe for it on this blog like our spicy meat sauce, our bison bolognese, and our pumpkin meat sauce.
We particularly like this one for busy days because we can get it all ready, put it into our slow cooker and then dinner is ready and waiting for our family. Anything that makes dinner time easier, is a plus in our book.
Bonus points that it is high in protein, satisfying, and full of flavor. Oh and if you have leftovers, you can use it to make this no boil noodle lasagna.

Recipe ingredients

- Olive oil– the veggies and ground beef sautee in this. A good quality olive oil always adds nice flavor.
- Garlic and carrots– these add flavor to the meat as it browns.
- Ground beef– we like using ground beef with a little fat in it but feel free to use a low fat ground beef if that is what you prefer.
- Tomato paste and marinara– these add tomato flavor to the sauce.
- Beef broth– this keeps the sauce from getting dry.
- Salt, pepper, onion powder, dried oregano, dried basil– these herbs and spices are added to the sauce to deepen the flavors of the sauce.
- Honey– this balances the acidity of the tomatoes.
- Dark chocolate– this is optional! We love adding a piece of dark chocolate to our sauces since it adds such a great flavor.

- Instead of honey, you can use maple syrup.
