🧂 Ingredients (Serves 6–8)

🥩 Meatloaf base

• 2 lbs ground beef (80/20 preferred for juiciness)
• 1 cup breadcrumbs
• 2 eggs
• ½ cup milk
• 1 packet French onion soup mix (key flavor)
• 1 tbsp Worcestershire sauce
• 1 tsp garlic powder
• ½ tsp black pepper
• ½ tsp salt (optional—soup mix is already salty)

---

🧅 Onion layer

• 2 large onions, thinly sliced
• 2 tbsp butter
• 1 tbsp olive oil
• 1 tsp sugar (helps caramelize)
• ½ cup beef broth

---

🧀 Topping

• 6–8 slices Swiss cheese (or Gruyère for richer flavor)

---

🔥 Instructions

1. Caramelize the onions (important flavor step)

1. Heat butter + olive oil in a skillet
2. Add sliced onions + sugar
3. Cook on medium-low for 15–25 minutes, stirring often
4. Add beef broth and cook until soft, golden, and jam-like

👉 This is what gives the “French onion” depth.

---

2. Mix the meatloaf

In a large bowl combine:

• ground beef
• breadcrumbs
• eggs
• milk
• French onion soup mix
• Worcestershire sauce
• garlic powder
• pepper

Mix gently—don’t overwork.

---

3. Shape & place in crockpot

• Shape mixture into a loaf form
• Place in greased crockpot
• Press caramelized onions on top (and slightly over sides)

---

4. Slow cook

• LOW: 6–7 hours
• HIGH: 3–4 hours

👉 Meat should reach 160°F (71°C) internal temp.

---

5. Add Swiss cheese

• Place Swiss cheese slices on top
• Cover and cook 10–15 minutes until melted

---

6. Rest & serve

• Let sit 10 minutes before slicing
• Spoon extra onion juices over each slice

---

💡 Tips for best results

• Use 80/20 beef for juicy texture
• Don’t skip caramelizing onions—it defines the dish
• Swiss or Gruyère gives the most authentic French onion flavor
• Line crockpot with parchment for easier removal
• Letting it rest helps it hold shape when slicing
