Do these meatballs freeze well?
If you are lucky enough to have any leftover meatballs, they freeze well. Just place them in an airtight container and stick them in the fridge.
When ready to eat, just thaw and reheat. They reheat well in a microwave oven.
We don’t freeze the mashed potatoes or mashed cauliflower that we serve these meatballs over. You can make a fresh mash for your meatballs.
How to make salisbury steak meatballs:
- In a mixing bowl add 1/2 cup of chopped mushrooms, 1/2 pound of hamburger, 1/2 pound ground turkey, chopped onion, tomato paste, egg, ground oatmeal, salt and pepper to taste, and 1/4 cup beef broth.

- Mix until well combined. We find that using our hands works best, especially when forming the meatballs.
- Shape meat mixture into 1 1/2 inch meatballs.

- In a separate bowl mix together the flour, remaining beef broth, remaining minced onions, tomato paste, and Worcestershire sauce. Stir together and set aside.

- Heat oil in a skillet and brown meatballs on all sides. They don’t need to cook through. Just brown the outside edge.

- Place meatballs in a slow cooker. Sprinkle with sliced mushrooms.
- Pour sauce over all.

- Cook on low for about 6 hours. It will smell amazing!

- You can serve these meatballs on their own, or you can serve them over mashed potatoes. To make it a healthy dish, we serve them over mashed cauliflower. Our kids had no idea it was mashed cauliflower. WIN!

These meatballs look delicious! I can’t wait to try them. I’ll probably use my Instant Pot. Thanks!
Made this recipe earlier in the week and my twin, twelve year-old daughters loved it so much that I made it (again) for dinner tonight. It’s s keeper! Thanks for sharing this great recipe.
These look good, but my family doesn’t like mushrooms. Do I need them? or Can I grind them up so they can’t see them.
You can leave them out, or grind them up.
I making this right now so you by be able to help me, but maybe you can fix the recipe for future users. (I subscribe to the meal plan and came here hoping to find a corrected recipe.)
The onion is listed in the ingredients but it doesn’t say how much good in the meatballs and how much goes in the sauce. It just says to add remaining onions to the sauce. But how much was supposed to go in the meatballs? I’ll just wing it, but maybe you can fix the recipe for the next person who might not like to wing it. Thanks.
Thanks for catching that. the corrections have been made.
Can I add white rice to the bottom of the freezer container then pour this over it?
You might want to freeze it separately so that the rice doesn’t soak up all the liquid before freezing.
Can I used cracker crumbs instead of oatmeal?
In the long instructions it mentions mustard powder?…but no where else.
Thanks for catching that. No mustard powder in this recipe.
This looks delicious! Can I use frozen meatballs? How would the cooking time change? Thanks!
I’m sure frozen meatballs would work in this recipe too. They are precooked so the cooking time would be less, they just need to be cooked through. You would also want your onions cooked through also.
Mine did not hold together at all. They were meatballs until the crock pot said nope. I’ll stick to McCormick meatloaf mix 3TBS per 2 lbs ground beef after it’s drained, 2 pieces of bread and 2 cps oat O’s ground fine, 2 eggs & 1/2 cp milk. Just use a beef mushroom gravy either homemade or store bought.
