Introduction

These aren't your mama's meatballs--they're better! Lean but packed with flavor, they cook all day while you're away. These aren't your mama's meatballs--they're better! Lean but packed with flavor, they cook all day while you're away.
Number of Servings: 4

Ingredients

    1 large white or yellow onion, quartered
    4 garlic cloves
    1 red bell pepper, cored and cut in half
    8 ounces sliced mushrooms
    1 tablespoon Italian seasoning
    1/2 teaspoon red pepper flakes
    1/4 teaspoon black pepper
    16 ounces lean ground beef (94% lean)
    1 slice whole wheat bread, crust removed and processed into bread crumbs
    1 egg yolk
    2 tablespoons grated Parmesan cheese, divided
    2 1/2 cups prepared low-sodium marinara sauce, divided
    fresh basil or parsley for garnish (optional)

Tips

Use a food processor to make quick work of chopping all those veggies. If you don't have one, you can mince them instead. You want the veggies to be finely minced--this will ensure moist but not soggy meatballs.

If cooking longer than five hours, increase the water in the recipe to 3/4 cup.


Directions

Pulse the onion in a food processor until finely chopped.

Coat a large saucepan with cooking spray and place over medium-high heat. Add the onion and cook for about four minutes, until it starts to soften.
Meanwhile, add the remaining vegetables to the food processor (no need to clean it after chopping the onions) and pulse until they are finely chopped.
Add the veggies to the pan, stir and cook for another four minutes, until their juices start to evaporate. Add the herbs and spices, stir, and remove from heat.

Transfer 1 cup of the vegetables to the food processor and pulse several times. Layer the rest in the bottom of the slow cooker.

Transfer the pureed veggies from the food processor to a medium bowl. Refrigerate for five minutes to cool slightly.
Add the beef, bread crumbs, egg yolk, and one tablespoon of Parmesan cheese to the bowl with the pureed vegetables. Using a fork or slotted spoon, thoroughly mix. Scooping two tablespoons at a time into your hands, roll the meatballs between the palms of your hands.
Place the meatballs into a large microwave-safe dish. Microwave on high for five minutes to release some of the fat (optional).

Pour 1 1/2 cups of the marinara sauce into the bottom of the slow cooker along with 1/2 cup water and stir to combine with the vegetables.

Place the meatballs on top in a single layer. Pour on the rest of the marinara sauce, cover and cook on low for three to five hours. Garnish the cooked meatballs with the remaining Parmesan cheese and herbs.

Serving Size: Makes 4 servings, 3 meatballs per person

    The easiest way to make meatballs is to bake them. Use the broiler pan, cover the bottom with foil, spray the slotted grill & place the meatballs on it. Bake for 30 minutes or so until done. The grease drips out onto the foil - easy cleanup. The meatballs are all moist, and they freeze well. - 8/28/13

    I don't understand the vegetables mixed with the marinara in the crockpot? And I wish this was something that wouldn't take forever and dirty a ton of pans in the morning: this is NOT a "before the workday" recipe. Minced veggies and pureed are very different! That will affect the meatball texture. - 8/28/13

    I would try this with ground turkey or chicken instead of the beef, that should cut down on the calories wouldn't it? And serve over vegetable spaghetti instead of pasta - yum! - 9/27/13

    These are too time consuming for the taste. You can make them much easier for a lot less time. I don't think I will be making this recipe again. - 1/9/15

    This really wakes up the meatballs! The flavors infused in the hamburger added great flavor. No time for slow cooker method so baked them in the oven instead then added to the sauce. I used this recipe again for hamburger patties cooked on the grill too. A little time consuming but worth the effort. - 9/10/14

    Delicious!!! I used Panko breadcrumbs. I have a basic meatball recipe that is quite similar and freeze several batches so that I have them on hand. They thaw quickly. - 8/28/13

    The veggies are divided -- only 1 cup of them are puréed to add to the meat mixture. The rest are minced to add to the sauce. I used to steam/purée zucchini and add to spaghetti sauce as a way to sneak veggies into my non-veggie-eating son. He was none the wiser. :-) - 8/28/13

    The serving size is 3 meatballs per person, but it says that they are lean.

    I am assuming that the vegies in the crock pot are to combine with the marinara to make the sauce. The vegies are choped first and then cooked slightly. The one cup is then pureed to add to meat.It goes pretty fast and you only have three utinsels to clean. Food Processor,Skillet and Bowl. - 8/28/13

    Didn't like the flavor. I chop onion, garlic and shred a carrot. Add 1/2 cup of rice, 1 egg and black pepper. Then cook in a frying pan and drain the grease. Much better flavor than this. Cover with a can of tomato soup. - 7/11/16

    Being Italinan this was way to complicated. I saute onions, mushrooms and garlic in a dutch oven, when soften, add 1 C red wine, then boil off and then add 1 jar marinara sauce (no sodium) while that is cooking, make my meatballs (no veggies) use 98/2 meat, so no fat. Roll meatballs add to sauce. - 8/23/15

    I use a 1.5 tbsp scoop to portion these-- scoop directly onto a cookie sheet and bake at 350- it gives half round meatballs but no-one seems to mind, and they stay on sandwiches better :-) - 4/29/21

    Way too much work. The veggies do not have to be fried, they will cook within the meatballs and slow cooker. I bake mine first to get rid of the grease and then slow cook. - 7/17/19

    It's not safe to put raw ground meat in a slow cooker.
    Bake them in an oven is best and not so much mess

    This is probably tasty, but too much effort and time for the results for my needs. Other comments reinforce my thoughts. Besides, it's not as if meatballs are super-high calorie anyway. I can just buy them. - 8/23/18
