These 2-ingredient Slow Cooker French Onion Meatballs aren’t just easy — they’re delicious too! With frozen turkey meatballs and a can of French onion soup, you can toss everything into your crock pot and let it do the work. Perfect for busy weeknights when you need dinner with almost no prep.
I used to be a kitchen overachiever who thought it was “cheating” to use store-bought meatballs. These days, I’m grateful for shortcuts that make healthy eating easier. While I usually grab frozen turkey meatballs to keep the points low, you can use beef, chicken, or even homemade meatballs if you prefer.
Serve these savory meatballs with creamy low-calorie mashed potatoes, rice, or easy 2-ingredient shredded zucchini casserole for a quick family-friendly dinner. They also freeze beautifully, making them a great meal prep option.

Ingredients and Substitutions
- Frozen Meatballs – I use turkey meatballs to keep the calories and WW Points lower. Beef, chicken, or vegetarian meatballs will also work. If you prefer, you can make your own homemade meatballs.
- French Onion Soup – A can of condensed French onion soup creates the savory sauce. Choose reduced-sodium soup to keep the recipe lighter. You can also swap in homemade French onion soup if you have some on hand.
Step-by-Step Instructions
Slow Cooker Method
- Add ingredients. Place frozen meatballs into the slow cooker. Pour the French onion soup over the top and stir to coat.
- Cook. Cover and cook on LOW for 4–6 hours or HIGH for 2–3 hours, until meatballs are heated through and tender.
- Serve. Stir gently and serve meatballs with sauce over mashed potatoes, rice, noodles, or zucchini noodles.
Instant Pot Method
- Add ingredients. Place frozen meatballs in the Instant Pot (affiliate link) insert. Pour French onion soup over the top.
- Pressure cook. Lock the lid and set vent to Sealing. Cook on High Pressure for 5 minutes. Allow 5 minutes of natural release, then quick release any remaining pressure.
- Serve. Stir gently and serve warm with your favorite sides.
Recipe Notes and Variations
- Keep it light: Using frozen turkey meatballs helps keep the calories and WW Points lower, but beef, chicken, or plant-based meatballs all work.
- Homemade option: If you’d rather skip store-bought, use your favorite homemade meatballs. You can add them raw to the slow cooker, or brown them first for extra flavor and firmer texture.
- Sauce boost: For a richer flavor, stir in a splash of Worcestershire sauce or a teaspoon of balsamic vinegar before cooking.
- Add veggies: Make it a one-pot meal by adding sliced mushrooms, bell peppers, or zucchini during cooking.
- Serving ideas: These French onion meatballs are delicious over mashed potatoes, rice, egg noodles, or spiralized zucchini noodles.
We enjoyed our slow cooker French onion meatballs with mashed potatoes and broccoli. They would be good with rice, cauliflower rice, noodles or zucchini noodles too.

I didn’t add water. If you want a more diluted flavor you certainly can. ~Martha
Recipe sounds yummy. Although high in sodium. Will make my own onion soup. Thanks for sharing.
Love this recipe ! Simple ,quick and easy. I did add 2 tbsp of Worcestershire Sauce and 2 tbsp of A1 Steak Sauce for a little extra tang and topped with shredded cheddar cheese and served on toasted buns .
Hi Tim, Love the idea of adding a little Worcestershire and A1 steak sauce for added tang. Thanks for taking the time to let us know. ~Martha
How wou li d you cook these in an Instant Pot?
Hi Lynda, I haven’t tried them in the Instant Pot. Based on what I can see on the Internet I would place the onion soup in the pot and then add the meatballs. I would seal the vent and cook on High Pressure for 5 minutes and then do a Quick Release. Would love to know how they turn out for you. ~Martha
Hi! Did you defrost the meatballs first? Or use 4 cans with frozen. Still cook as stated if put in frozen? Thanks
Hi Annemarie, I used un-defrosted frozen meatballs. Hope this helps. ~Martha
This recipe is delicious…so easy to prepare! I recently purchased a 3 compartment slow cooker. Since I only cook for 2, the small cookers are perfect to make delicious simple nourished meals on the weekend and enjoy them all week long. It feels good to eat healthy as well as delicious foods and to know that I am not deprived.
Delicious and simple!
Where can turkey meatballs be purchased?
Hi Carol, I’m able to find turkey meatballs in the freezer sections of my grocery store. I’ve also seen them at Walmart and Trader Joes and Costco (in the refrigerator section. Hope this helps. – Martha
Made these today OMG they are delicious. I used frozen meatballs and 4 cans of French Onion soup. I’d love to try with Turkey Meatballs if I can find some.
Can this be used in Instant Pot? If so, any changes to recipe?
Hi Peggy, I haven’t done it in the Instant Pot. I’m sure you could do it in the Instant Pot on the Slow Cooker Setting, but I have never tried it using the pressure cooker setting.
