Cooking Instructions for French Onion Meatballs

• Blend Meatball Mixture Gently mix ground beef with breadcrumbs, Parmesan, egg, garlic powder, onion powder, salt, pepper, and parsley until ingredients are just combined.
• Shape Meatballs Roll the meat mixture into bite-sized balls, creating uniform rounds about the size of a golf ball.

Tips to Enhance Flavor in Onion Meatballs

• Let the meat mixture rest for 15 minutes before forming meatballs to help them hold together more effectively.
• Brown meatballs in a skillet before adding to the slow cooker to develop a deeper, richer caramelized exterior.
• Replace traditional breadcrumbs with gluten-free breadcrumbs or crushed pork rinds to make the recipe celiac-friendly.
• Swap beef for ground turkey or chicken and use almond flour instead of breadcrumbs for a lighter protein option that's keto-friendly.
• Prepare meatballs in advance and freeze uncooked for up to 3 months, allowing for quick meal preparation on busy days.

Serve Up French Onion Meatballs Like a Pro

• Comfort Plate Pairing: Serve these savory meatballs over creamy mashed potatoes or buttery egg noodles to soak up the rich French onion sauce, creating a hearty and satisfying meal.
• Wine Companion Choice: Complement the deep, caramelized flavors with a medium-bodied red wine like Pinot Noir or Beaujolais, which will enhance the meatballs' robust taste profile.
• Elegant Garnish Touch: Sprinkle fresh chopped parsley or green onions on top just before serving to add a bright, fresh contrast to the rich and intense meatball dish, providing a pop of color and subtle herbaceous notes.
• Bread Basket Bonus: Offer crusty French bread or garlic crostini on the side for guests to mop up the delicious French onion sauce, ensuring no flavorful drop goes to waste.

Store and Reheat French Onion Meatballs Smoothly

• Shape meatballs in advance and refrigerate for up to 24 hours before cooking, saving time during busy weeknights and allowing flavors to meld.
