Why You’ll Love This Recipe
- Only 4 main ingredients
- Easy slow cooker preparation
- Rich French onion-inspired flavor
- Tender beef patties and savory gravy
- Perfect over mashed potatoes
- Great for busy weeknight dinners
Ingredients
- 1 1/2 pounds ground beef
- 1 packet dry French onion soup mix
- 1 can (10.5 ounces) condensed French onion soup
- 1 cup shredded Swiss or mozzarella cheese
Salt and black pepper are optional, since the soup mix and condensed soup are already seasoned.
Step-by-Step Instructions
1. Shape the Burger Steaks
Place the ground beef in a bowl and gently form it into 5–6 oval-shaped patties.
Don’t overwork the meat. Gentle handling helps keep the burger steaks tender.
2. Layer the Slow Cooker
Pour about half of the condensed French onion soup into the bottom of the slow cooker.
Arrange the beef patties over the soup.
Sprinkle the dry French onion soup mix evenly over the patties.
Pour the remaining soup over the top.
3. Slow Cook
Cover and cook on LOW for 5–6 hours or HIGH for 3–4 hours.
The beef should reach 160°F (71°C) for food safety.
The patties will release juices as they cook, combining with the onion soup to create a rich gravy.
4. Add the Cheese
During the final 10–15 minutes, sprinkle shredded Swiss or mozzarella cheese over the burger steaks.
Cover again and let the cheese melt.
5. Serve
Carefully transfer the burger steaks to plates and spoon plenty of the onion gravy over the top.
Serve immediately with your favorite comfort-food sides.
Helpful Tips
Don’t Overmix the Beef
Mixing isn’t really necessary for this recipe. Simply shape the ground beef into patties. Overworking the meat can make the finished burger steaks dense.
Use Swiss Cheese for Classic Flavor
Swiss cheese gives the dish a flavor reminiscent of French onion soup. Mozzarella works well if you prefer a milder, extra-melty topping.
Check the Beef Temperature
Because these are made with ground beef, use a food thermometer to make sure the center reaches 160°F (71°C).
Want Thicker Gravy?
If the cooking liquid is thinner than you’d like, transfer it to a saucepan after cooking. Mix 1 tablespoon cornstarch with 2 tablespoons cold water, stir it into the gravy, and simmer until thickened.
What to Serve With Burger Steaks
These French onion burger steaks are especially delicious over:
- Creamy mashed potatoes
- Buttered egg noodles
- White rice
- Roasted potatoes
- Garlic mashed potatoes
Add a vegetable such as:
- Green beans
- Roasted carrots
- Broccoli
- Peas
- Simple garden salad
Storage
Store leftover burger steaks and gravy in an airtight container in the refrigerator for 3–4 days.
For longer storage, freeze the cooked burger steaks with gravy for up to 2–3 months.
Reheating Instructions
Place the burger steaks and gravy in a covered skillet over medium-low heat.
Warm gently until heated through. Add a small splash of beef broth if the gravy has become too thick.
Individual servings can also be reheated in the microwave.
Frequently Asked Questions
Can I use ground turkey?
Yes, but the flavor and texture will be different. If using ground turkey, cook it to 165°F (74°C).
Can I use provolone instead of Swiss cheese?
Absolutely. Provolone is an excellent choice and melts beautifully over the burger steaks.
Can I add onions?
Yes. Sliced yellow onions can be added underneath and around the patties for an even stronger French onion flavor.
Can I make this without cheese?
Yes. The burger steaks will still be flavorful because the onion soup creates a savory gravy.
Can I make these ahead of time?
Yes. Cook the burger steaks completely, refrigerate them with the gravy, and gently reheat before serving.
