In a large bowl combine beef, Oats, eggs, Salt, Pepper, 1 Pkg. of Lipton Onion soup, Evaporated Milk (adds a nice moisture and flavor), and minced onion.
Work gently together with hands.
Scoop in to meatballs using a cookie scoop, or roll with hands.
In a skillet, cook on medium high heat turning to brown all sides. They are also great if you would rather bake them in the oven. Either way, cook meat through.
Place in the Crock-pot.
In another bowl, whisk together 2 cans of cream of celery and 2 cans of regular milk.. just measure the milk in the cans! You can thin more with the milk if desired. Whisk in a package of Lipton onion soup mix. Pour this mixture over meatballs.
Cover and cook on low for 5-6 hours or high 3-4.
Notes
Serve with mashed potatoes, lingonberry sauce, and cooked or pickled cabbage.
