Ingredients 🧅🧀
- 2 lbs ground beef
- 1 envelope French onion soup mix
- ½ cup breadcrumbs
- 2 eggs
- ¼ cup milk
- 1 cup caramelized onions (see tip below)
- 1 cup shredded Swiss cheese
- Chopped fresh parsley, for garnish
Instructions 👩🍳
1. Mix the Meatloaf Base:
In a large bowl, combine the ground beef, French onion soup mix, breadcrumbs, eggs, and milk. Mix until well combined but avoid overworking the meat.
2. Shape and Cook:
Form the mixture into a loaf shape and place it directly into the crockpot. Cover and cook on low for 4 hours.
3. Top with Onion & Cheese:
During the last 15 minutes of cooking, carefully layer the top of the meatloaf with caramelized onions and shredded Swiss cheese. Cover and continue cooking until the cheese is melted and bubbly.
4. Garnish & Serve:
Sprinkle with chopped parsley for a pop of color and serve warm—slice it up and enjoy every cheesy, oniony bite!
Tips for Perfect Caramelized Onions
Slice 2–3 yellow onions thinly and cook in a bit of butter over low heat for 30–40 minutes, stirring occasionally until deeply golden and sweet. These can be made ahead and stored in the fridge for up to a week.
Serving Suggestions
Serve with creamy mashed potatoes, roasted green beans, or even a crisp garden salad to round out the meal. A drizzle of extra pan juices over each slice makes it even better!
