Recipe: French Onion Soup Burgers
Ingredients
- 1 lb ground beef (80/20 blend for juiciness)
- 1 large onion, thinly sliced
- 2 tablespoons butter
- 1 tablespoon olive oil
- 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried thyme)
- Salt and pepper, to taste
- 4 slices Gruyère cheese (or Swiss cheese)
- 4 hamburger buns (preferably brioche)
- Optional: beef broth for added moisture
Directions
- Caramelize the Onions:
- In a large skillet, heat the butter and olive oil over medium heat. Add the sliced onions and cook slowly, stirring frequently, for about 20-25 minutes until they are golden brown and caramelized. Stir in the thyme and season with salt and pepper. If the onions start to dry out, add a splash of beef broth to keep them moist. Remove from heat and set aside.
- Prepare the Burger Patties:
- While the onions are caramelizing, divide the ground beef into four equal portions and shape them into patties. Make a slight indentation in the center of each patty to prevent them from puffing up while cooking. Season both sides with salt and pepper.
- Cook the Burgers:
- Preheat your grill or a skillet over medium-high heat. Cook the burger patties for about 4-5 minutes on each side for medium doneness, adding a slice of cheese on top of each patty during the last minute of cooking. Cover the skillet or grill to help the cheese melt.
- Assemble the Burgers:
- Toast the hamburger buns lightly on the grill or in a toaster. Place the cooked burger patties with melted cheese on the bottom halves of the buns. Top generously with caramelized onions, then place the top halves of the buns on each burger.
- Serve:
- Serve the French Onion Soup Burgers immediately with your favorite sides, such as fries or a fresh salad. Enjoy the delightful combination of flavors!
Storing and Preserving
French Onion Soup Burgers are best enjoyed fresh, but you can store leftover components separately in the refrigerator for up to 3 days. Keep the cooked patties, caramelized onions, and buns in airtight containers. To reheat, warm the patties in a skillet or microwave, and toast the buns if desired. Reheat the onions gently to maintain their texture.
Common Mistakes and Troubleshooting
- Undercooking the Onions: Caramelizing onions takes time; be patient to develop their sweetness and flavor. Avoid cooking on high heat, as this can cause them to burn rather than caramelize.
- Overcooking the Burgers: Use a meat thermometer to ensure the burgers reach an internal temperature of 160°F (71°C) for medium doneness. Overcooking can lead to dry burgers.
- Cheese Not Melting: Covering the pan or grill during the last minute of cooking helps the cheese melt evenly. If using a skillet, you can also add a splash of water and cover to create steam.
FAQs
- Can I use different types of cheese?
Yes, you can use any cheese you like, such as cheddar or provolone, but Gruyère or Swiss are traditional choices for a French onion flavor. - Can I make the caramelized onions in advance?
Absolutely! Caramelized onions can be made ahead of time and stored in the refrigerator for up to 5 days. Just reheat them before serving. - What can I use instead of beef?
You can substitute ground turkey or chicken for a lighter option, or use plant-based ground meat for a vegetarian version. - How can I make these burgers spicier?
Add some cooked bacon, sautéed jalapeños, or a spicy sauce to your burgers for an extra kick! - Can I freeze the burger patties?
Yes, you can freeze the shaped burger patties. Just wrap them tightly in plastic wrap and store them in an airtight container for up to 3 months.
