Easy Steps for Onion-Infused Meatball Bliss

Step 1: Caramelize Onions

• Onions
• Garlic
• Bay leaves
• Salt

Stir frequently and cook until onions turn deeply golden and reduce in volume, about 45 minutes. If the pan becomes dry around the 30-minute mark, splash in some water.

Step 2: Enhance Onion Flavor

Stir in thyme and black pepper, cooking for 1 minute until fragrant. Add butter, scraping the pan to loosen dark bits. Remove bay leaves and transfer onions to a plate to cool slightly.

Step 3: Prepare Meatball Mixture

• Ground beef
• Egg
• Panko
• Salt
• Pepper

Roughly chop half the cooled onions and mix into the meat mixture using clean hands until evenly combined.

Step 4: Shape Meatballs

Divide the meat mixture into 16 equal portions. Create 1 1/2-inch balls by quartering the mixture, then quartering each portion again.

Step 5: Brown Meatballs

Heat of olive oil in the skillet over medium-high heat. Add meatballs, spacing them apart, and cook until browned on all sides, about 10-12 minutes.

Step 6: Create Sauce

• Chicken broth
• Remaining onions
• Mustard
• Worcestershire sauce

Simmer for 10 minutes, stirring occasionally, until the sauce thickens and darkens.

Step 7: Melt Cheese Topping

Preheat broiler on low. Sprinkle Gruyere cheese over the meatballs and sauce. Broil for about 2 minutes until cheese melts completely.

Step 8: Serve and Store

Serve hot with toasted baguette slices. Store leftovers in the refrigerator for up to 5 days.

Tips for Juicy Meatballs with a Caramelized Kick

• Caramelize Onions Slowly: Take your time with onions, stirring frequently and keeping heat low to develop deep, sweet flavor without burning.
• Choose Quality Ground Beef: Select 80/20 ground beef for juicier, more flavorful meatballs that won't dry out during cooking.
• Mix Gently: Use clean hands to combine meatball ingredients, avoiding overworking the meat to keep texture light and tender.
• Control Skillet Temperature: Maintain medium-high heat when browning meatballs to create a perfect golden crust without burning.
• Layer Cheese Strategically: Use freshly grated Gruyere and spread evenly to ensure complete, even melting under the broiler.

Keep Those Meatballs Tender After Reheating

• Refrigeration: Transfer meatballs and sauce to an airtight container, ensuring they're completely cooled before sealing. Store in the refrigerator for up to 5 days, maintaining maximum flavor and texture.
• Reheating: Gently warm meatballs in a skillet over medium-low heat, adding a splash of chicken broth to prevent drying. Stir occasionally and cook until heated through, typically 5-7 minutes. Alternatively, microwave in 30-second intervals, stirring between each to distribute heat evenly.
• Freezing: Wrap individual portions in freezer-safe containers or heavy-duty plastic bags. Freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.

Pairings That Love French Onion Flavor

• Pair with Bold Red Wine: Select a robust Cabernet Sauvignon or Syrah to complement the rich, savory flavors of the meatballs. These wines have enough depth and tannins to stand up to the meaty, caramelized onion sauce.
• Serve with Crusty French Bread: Use a freshly toasted baguette to soak up the delicious onion gravy. The crispy exterior and soft interior provide perfect textural contrast to the tender meatballs.
• Match with Crisp Green Salad: Create a light side of mixed greens with a tangy vinaigrette to cut through the dish's richness. Incorporate some bitter greens like arugula to balance the meatballs' intense flavors.
• Recommend Craft Beer Pairing: Choose a Belgian-style brown ale or a malty amber beer. These brews offer caramel notes that beautifully echo the caramelized onions and provide a refreshing counterpoint to the hearty meatballs.

Flavor Swaps That Elevate This Classic

• Rustic Mediterranean Meatballs: Replace ground beef with a mix of lamb and beef for a richer flavor profile. Swap Gruyere with crumbled feta cheese and add chopped fresh mint to the meat mixture. Top with a dollop of tzatziki sauce for extra Mediterranean flair.
• Spicy Smoky Meatball Remix: Incorporate chipotle peppers in adobo sauce into the meat mixture for a smoky kick. Use smoked paprika when caramelizing onions and substitute Gruyere with pepper jack cheese. Serve with jalapeño cornbread for added heat.
• Italian-Inspired Meatball Variation: Mix ground pork and beef together for the base. Add grated Parmesan and chopped fresh basil to the meat mixture. Replace Gruyere with fresh mozzarella and drizzle with marinara sauce before broiling. Garnish with fresh parsley and serve over creamy polenta.

Instructions

1. Caramelize onions in a large skillet with olive oil (30 milliliters or ) over medium heat, adding whole garlic cloves, bay leaves, and a pinch of salt. Stir consistently, allowing onions to transform into a deep golden hue and reduce in volume over approximately 45 minutes.
2. If the pan appears dry around the 30-minute cooking mark, introduce a small splash of water to prevent burning and maintain moisture.
3. Incorporate fresh thyme and cracked black pepper, stirring for 1 minute to release aromatic flavors. Add unsalted butter (14 grams or ), gently scraping the pan to incorporate caramelized remnants. Discard bay leaves and transfer onions to a separate plate for cooling.
4. In a spacious mixing bowl, combine ground beef (453 grams or ), a beaten egg, panko breadcrumbs (60 grams or ), kosher salt, and freshly ground black pepper.
5. Finely chop half of the cooled caramelized onions and fold them into the meat mixture, blending thoroughly using clean hands until ingredients are evenly distributed.
6. Systematically divide the meat mixture into 16 uniform portions by first quartering the mixture, then subdividing each quarter into four equal meatballs, each measuring approximately 1 1/2 inches in diameter.
7. Heat additional olive oil (30 milliliters or ) in the skillet over medium-high heat. Carefully place meatballs with adequate spacing, browning them evenly on all surfaces for 10-12 minutes.
8. Dust the browned meatballs with all-purpose flour (15 grams or ), gently tossing to ensure a light, even coating and cooking the flour for 1 minute.
9. Pour chicken broth (240 milliliters or ), remaining caramelized onions, Dijon mustard (15 milliliters or ), and Worcestershire sauce (15 milliliters or ) into the skillet. Simmer for 10 minutes, stirring intermittently until the sauce thickens and deepens in color.
10. Activate the broiler on low setting. Generously sprinkle grated Gruyere cheese (113 grams or ) over the meatballs and sauce, then broil for approximately 2 minutes until the cheese melts and develops a golden crust.
11. Serve immediately alongside toasted baguette slices. Store any remaining portions in an airtight container within the refrigerator for up to 5 days.
