Category: Satisfying Main Courses for Every Occasion

Salisbury steak meatballs made in the slow cooker bring all the comfort of a classic dinner with minimal effort. Frozen meatballs, mushrooms, onions, and garlic go straight into the slow cooker, absorbing flavor from beef broth, soy sauce, and Dijon mustard as they simmer. The rich, homemade gravy comes together as the stew cooks, yielding tender meatballs perfect to spoon over mashed potatoes or noodles. With a brief prep and no need to thaw meatballs in advance, this dish is ideal for busy weeknights. Leftovers keep well for several days, making lunch or dinner a breeze. Simplicity and hearty flavor in one comforting bowl.

Salisbury steak meatballs are my answer to cozy weeknight dinners without a fuss. With frozen meatballs as the shortcut, you only need to gather a few ingredients and let your slow cooker do the rest. By dinnertime, you get tender meatballs hugged by a rich mushroom gravy that tastes just like something Grandma used to make.

I first made this on a rainy day when I wanted comfort food but had zero energy for anything complicated. Now these meatballs are on regular rotation because everyone always cleans their plate.

Ingredients

  • Frozen meatballs: beef or turkey both work well and save time so choose your favorite for best flavor
  • Sliced mushrooms: bring earthiness and soak up the savory sauce look for fresh and firm mushrooms with tight caps
  • Chopped yellow onion: adds sweetness and depth choose onions with dry papery skins and no soft spots
  • Garlic: minced for aroma and punch use fresh cloves for a bigger flavor boost
  • Butter: essential for a silky roux and extra richness always choose unsalted to control saltiness
  • Flour: thickens the gravy use allpurpose for the smoothest texture
  • Soy sauce: provides umami and a deeper color pick a low sodium variety for control
  • Dijon mustard: for tang and subtle heat go for real Dijon not yellow for best results
