Tips to make Crockpot French Onion Meatballs

  1. Don’t overwhelm the crockpot: If yours is smaller, make in batches so everything cooks evenly.
  2. Swap it up: Ground turkey or chicken works well too if you want a lighter option.
  3. For richer flavor, sauté the onions in a pan before adding them to the crockpot—total game-changer!
  4. Season generously: Don’t be shy with the salt and pepper; seasoning is key.
  5. Garnish with fresh herbs for an extra layer of flavor and color—think parsley or thyme.

Variation

Want to mix it up? Try adding some sautéed mushrooms for an earthier taste or swap in vegan meatballs for a plant-based version. You could even toss in some fresh herbs like thyme or rosemary for a fragrant twist!
