How to Make Crockpot Spaghetti Sauce Step by Step
Cook the Beef: Brown and drain 3 pounds of lean ground beef in a frying pan, then place it in the crockpot.
Add the Veggies: Add 1 diced yellow onion, 16 ounces of diced baby bella mushrooms, 6 ounces of diced medium black olives (if using), 2 tablespoons of Italian seasoning, 2 tablespoons of granulated sugar, and salt and pepper to taste. Stir to combine.
Add the Sauces: Pour in 28 ounces (1 large can) of petite diced tomatoes, 24 ounces (1 jar) of four cheese pasta sauce, and 64 ounces (2⅔ jars) of marinara sauce. Stir well.
Cook the Sauce: Set the crockpot on low for 6 hours or high for 3 hours.
Garnish and Serve: Serve with 2 pounds (2 boxes) of cooked spaghetti noodles, 8 ounces of fresh parmesan, and dried basil.
Yes, as the sauce continues to cook, it will thicken, especially if you remove the lid of the crockpot at any point.
Your sauce may turn out watery if you add too much liquid, or if you cook it for too long. A simple fix is to turn the heat up to high and remove the lid to evaporate excess liquid.
Please try not to call this a Bolognese sauce.I realize today’ S cooking styles vary,but having one believe black olives or jarred cheese sauce is a Bolognese is hard to accept.Love your recipes and at times are surely “different” than an original.Black olives are in a puttanesca sauce,yes? I may be an older time cook,but original recipes do not require exaggerated time to cook. Enjoy all that you make.
