Caramelized Onion Meatloaf Ingredients

Here’s what you’ll need to make this elegant Caramelized Onion Meatloaf:

• Ground Beef: 80/20 ground chuck is ideal for the best flavor and moisture.
• Yellow Onions: 2 large onions, sliced thin and caramelized slowly until golden and jammy.
• Butter: For caramelizing the onions to sweet perfection.
• Fresh Thyme: Fresh thyme leaves complement the sweet onions beautifully (dried works in a pinch).
• Beef Stock: Adds extra moisture and depth to the meat mixture.
• Breadcrumbs: Panko or regular dry breadcrumbs work well as a binder.
• Egg: Helps hold everything together.
• Salt & Pepper: To season perfectly.

How to Make Caramelized Onion Meatloaf

Making Caramelized Onion Meatloaf requires a bit of patience, but the results are absolutely worth it:

1. Caramelize the Onions: Melt butter in a large skillet over low heat. Add thinly sliced onions and cook slowly for 30-40 minutes, stirring occasionally, until they’re golden brown, soft, and jammy. Don’t rush this step—it’s where the magic happens! Let the onions cool completely.
2. Mix the Meat: In a large bowl, combine ground beef, most of the cooled caramelized onions (save about ⅓ cup for topping!), breadcrumbs, egg, beef stock, fresh thyme, salt, and pepper. Mix gently until just combined.
3. Shape the Loaf: Form the mixture into a loaf shape on a parchment-lined baking sheet or press into a loaf pan.
4. Bake: Bake at 350°F for 45 minutes, or until the internal temperature is close to 160°F.
5. Add Topping: Remove from oven and top with the reserved caramelized onions (and a sprinkle of Gruyere cheese if you’re feeling fancy!). Bake for 10 more minutes until the cheese melts and the meatloaf reaches 160°F internally.

Tips for the Best Caramelized Onion Meatloaf

Want your Caramelized Onion Meatloaf to turn out perfectly every time? Follow these expert tips:

• Patience is Key: Don’t rush the onion caramelization process! High heat will burn them, but low and slow heat makes them beautifully sweet and jammy. It’s worth the wait.
• Cool Those Onions: Adding hot caramelized onions directly to raw meat can start cooking the eggs prematurely and create an uneven texture. Always let them cool completely first.
• Use a Meat Thermometer: Don’t overcook your meatloaf! Pull it from the oven at exactly 160°F for perfect doneness and maximum juiciness.
• Season as You Go: Taste your caramelized onions and adjust seasoning. They should be slightly salty and perfectly sweet.

Caramelized Onion Meatloaf FAQs

Can I make the caramelized onions ahead for Caramelized Onion Meatloaf?
