These homemade Swedish Meatballs with a creamy mustard sauce can be made in the crockpot or baked. These meatballs from scratch can be prepped ahead of time and then frozen, making a great dinner choice for hectic days when you don’t have much time to meal prep! These meatballs are similar to the Ikea meatballs but the sauce is made with Worcestershire and sour cream instead of soy sauce and heavy whipping cream.
Prep time: 30-40 minutes.
Crockpot/slow cooker time: 2-4 hours
Bake time: 30 min.
Yield: 12 meatballs
For the homemade meatballs:
- 1 pound lean ground beef
- 1 large egg
- 1/4 cup whole milk
- 1/3 cup rolled oats
- 1/4 cup diced onion
- dash paprika
- 1/3 teaspoon salt
- 1/4 teaspoon nutmeg (optional)
- 1/3 teaspoon allspice
- 1/2 teaspoon garlic powder (optional)
- Oil for frying
For the Mustard sauce:
- 2 tablespoons salted butter
- 2 1/2 tablespoons flour (I tend to add two heaping tablespoons and 1/2 tablespoon, you can always add more broth if needed.)
- 1/2 cup whole milk
- 1 1/2 cup beef broth *See Note below.
- 1 tablespoon prepared yellow mustard (or to taste).
- 1 1/4 tablespoons Worcestershire sauce

Preheat oven to 375 (if baking the meatballs).
- Place ground beef in a medium sized bowl. Add milk, egg, rolled oats and diced onion, then add spices. Mix by hand until the meat feels smooth and the ingredients are well combined. Avoid over mixing for moist meatballs.
- Shape the meat mixture into 12 meatballs, then place on a tray and refrigerate for 30 minutes (this helps the meatballs to hold together while frying).
- While the meatballs are chilling in the refrigerator, melt butter in a sauce pan, then stir in flour until smooth. Whisk in the milk and broth then bring to a light boil, whisking rapidly until all the lumps are dissolved. Reduce heat and add mustard, Worcestershire sauce, paprika and salt. Whisk to combine then remove the sauce from heat and stir in the sour cream.
- Pour roughly 2-3 tablespoons of olive oil in a large non-stick frying pan. Heat over medium heat then add the chilled meatballs to the hot oil and fry for a minute or two on each side or until the meatballs have browned. *See Notes below if you are having trouble with the meatballs staying together while frying.
- Mix 1/2 cup of the sauce with 1/4 cup water and pour over the bottom of a 3-4 quart crockpot. Place meatballs on top of sauce then pour the remaining sauce over top. Cook on low for 2-4 hours if fresh and 3-5 hours if frozen, or until the internal temperature reaches 165. If baking the meatballs you can bake them in a 9 by 13 inch baking dish at 375 for around 30 minutes. Pour the sauce over the meatballs at the last ten minutes of baking. Note* fry then bake the meatballs until fully cooked (without sauce) before freezing. More Notes Below.
These meatballs are yummy paired with buttered noodles (link to a great recipe below) or mashed potatoes! Try my Amish Style Mashed Potatoes or Ultimate Crock Pot Mashed Potatoes.

Note* These meatballs are a little more wet than some (because we love moist meatballs). If you are having trouble with them falling apart while you are frying them even after they have been refrigerated, you can roll them in a bit of flour before frying.

Substitution:
You can use 1 1/2 cups water and two beef bouillon cubes instead of beef broth; dissolve bouillon cubes in the 1 1/2 cups hot water before adding to the sauce.

The sauce may need to be stirred after the slow cooking process. If you really want to avoid grease you can skip adding sauce to the meatballs before cooking and add 3/4 cup beef broth to the bottom of the slow cooker instead, then place meatballs on top. After the meat balls have cooked for an hour and a half or two, drain the excess grease and broth, then pour the sauce over the meatballs. Return the crock pot to low and cook until the sauce is heated through and smooth, and the meatballs are fully cooked.
