Slow Cooker French Onion Meatloaf

❤️ Introduction

This Slow Cooker French Onion Meatloaf is the ultimate flavor-packed comfort food mashup! Combining the rich, savory depth of classic French onion soup with juicy, tender homemade meatloaf, it slow-cooks to perfection before being blanketed in melted cheese and sweet, caramelized onions. 🤤

🛒 Ingredients

• The Meatloaf:
  • 2 lbs (900 g) ground beef
  • 1 cup Progresso Italian breadcrumbs
  • ½ cup grated Kraft Parmesan cheese
  • 2 large eggs
  • ⅓ cup milk
  • 1 packet French onion soup mix (or Lipton onion soup mix)
  • Salt and black pepper to taste
• The French Onion Topping & Base:
  • 2 large yellow onions, thinly sliced
  • 4 tbsp unsalted butter, cut into small cubes
  • 1 ½ cups (150 g) shredded Swiss or provolone cheese
  • Fresh parsley, chopped (for garnish)

👩‍🍳 Instructions

1. Prep the Slow Cooker: Lightly spray the inside of a 6-quart slow cooker with non-stick cooking spray.
2. Layer the Onions and Butter: Scatter half of the thinly sliced yellow onions across the bottom of the slow cooker and dot with half of the cubed butter.
3. Mix the Meatloaf: In a large mixing bowl, combine the ground beef, Italian breadcrumbs, Parmesan cheese, eggs, milk, French onion soup mix, salt, and black pepper. Use your hands to mix everything together gently until just combined (don’t overmix, or the meatloaf will get tough).
4. Shape and Place: Shape the meat mixture into a uniform loaf and place it right on top of the bed of onions inside the slow cooker. Scatter the remaining sliced onions and butter all around and on top of the meatloaf.
5. Slow Cook 🔥: Cover with the lid securely and cook on:
   • LOW for 5–6 hours
   • or
   • HIGH for 3–4 hours
   • (Note: Cook until the meatloaf is fully cooked through and tender.)
6. Melt the Cheese: During the last 15 minutes of cooking, remove the lid and blanket the top of the meatloaf generously with the shredded Swiss or provolone cheese. Spoon some of the soft, caramelized onions over the cheese, cover with the lid, and let it melt until bubbly and gooey.
7. Serve: Carefully transfer thick slices of the French onion meatloaf to plates, spooning those rich, sweet caramelized onions and melted cheese right over the top!

⭐ Tips for the BEST Results

• 🧅 Caramelized onion base: Cooking the onions low and slow underneath and around the meatloaf infuses the entire dish with authentic French onion flavor without needing to pre-sauté them on the stove.
• 🧀 Cheese choice: While Swiss and provolone give that classic French onion soup stretch and flavor, mozzarella or Gruyère work wonderfully too!

🍽️ What to Serve With It

• 🥔 Creamy garlic mashed potatoes to soak up the extra onion juices
• 🥗 A crisp green Caesar or garden salad
• 🫛 Steamed green beans or roasted asparagus

🧊 Storage & Freezing

• Refrigerator: Store leftover meatloaf in an airtight container for 3–4 days. Reheat individual slices in the microwave.
• Freezer: You can freeze cooked meatloaf slices without the melted cheese topping for up to 2 months. Thaw overnight and add fresh cheese when reheating.
