Ingredients You’ll Need
For the Burgers:
- 1 lb ground beef (80/20 blend for best flavor)
- 1/2 cup crumbled blue cheese
- 1 tsp Worcestershire sauce
- 1/2 tsp garlic powder
- 1/2 tsp onion powder
- Salt and pepper to taste
For the Caramelized Onions:
- 1 large yellow onion, thinly sliced
- 1 tbsp butter
- 1 tbsp olive oil
- Pinch of salt
- 1 tsp balsamic vinegar (optional)
For Assembly:
- Large butter lettuce leaves
- Additional blue cheese crumbles
- Dijon mustard (optional)
Step-by-Step Cooking Instructions
Step 1: Caramelize the Onions
Heat butter and olive oil in a skillet over medium-low heat. Add sliced onions and a pinch of salt. Cook slowly, stirring occasionally, for 20-25 minutes until golden brown and sweet. For extra flavor, add balsamic vinegar in the last 5 minutes.
Step 2: Prepare the Burger Patties
While onions cook, mix ground beef with Worcestershire sauce, garlic powder, onion powder, salt, and pepper. Form into 4 equal patties, creating a slight indentation in the center of each to prevent bulging during cooking.
Step 3: Cook the Burgers
Heat a grill or skillet to medium-high. Cook patties for 4-5 minutes per side for medium doneness. In the last minute of cooking, top each patty with blue cheese crumbles and cover to melt.
Step 4: Assemble the Lettuce Wraps
Place each cheese-topped patty on a large butter lettuce leaf. Top with caramelized onions and additional blue cheese if desired. Add mustard or your favorite low-carb condiments. Fold the lettuce around the burger and enjoy!
Expert Tips for Perfect Lettuce Wrap Burgers
- Choose the right lettuce: Butter lettuce or romaine hearts work best for their pliability and cup-like shape
- Patty thickness: Keep patties about 3/4-inch thick for even cooking
- Cheese selection: For stronger flavor, use gorgonzola; for milder taste, try Danish blue cheese
- Make ahead: Caramelized onions can be made 3 days in advance and reheated
- Extra flavor: Mix 1 tbsp of the caramelized onions into the ground beef before forming patties
Nutritional Information
Common Mistakes to Avoid
- Rushing the onions: Caramelizing takes time – don’t crank up the heat to speed it up
- Overhandling the meat: Mix just until combined to keep burgers tender
- Wrong lettuce choice: Avoid iceberg – it cracks too easily when wrapping
- Overcrowding the pan: Cook burgers in batches if needed for proper browning
Variations to Try
- Buffalo style: Mix hot sauce into the meat and top with blue cheese dressing
- Mushroom lovers: Add sautéed mushrooms to the caramelized onions
- Bacon boost: Add crispy bacon inside the lettuce wrap
- Turkey version: Use ground turkey and goat cheese for a lighter option
FAQs About Lettuce Wrap Blue Cheese Burgers
Can I make these burgers ahead of time?
You can prepare components ahead – cook and refrigerate patties for up to 3 days, and caramelized onions keep for 5 days. However, assemble just before eating to prevent soggy lettuce.
What’s the best way to store leftovers?
Store components separately: cooked patties in an airtight container for 3-4 days, onions for 5-7 days. Reheat patties gently in a skillet or microwave before assembling fresh lettuce wraps.
Can I cook these on the grill?
Absolutely! Grill over medium direct heat. Use a grill basket for the onions or cook them indoors while grilling the burgers outside.
How can I make these dairy-free?
Substitute the blue cheese with dairy-free alternatives like cashew-based “blue cheese” or simply omit it and add extra umami flavors with mushrooms or soy sauce in the patties.
What sides pair well with lettuce wrap burgers?
Try roasted Brussels sprouts, zucchini fries, a crisp green salad, or cauliflower mash for low-carb options. For non-dieters, sweet potato fries make a delicious accompaniment.
