Cheesy Smashed Burgers
with Old Bay Asparagus, Caramelized Onion & Special Sauce
- Eggs
- Milk
- Wheat
- Soy
These burgers are sure to be a smash hit. The secret is all in the texture—the crispy, craggy edges, achieved when balls of ground beef are pressed down in a hot pan with a spatula to create super-thin, crispy burgers. Topped with gooey white cheddar, the patties are sandwiched between potato buns with caramelized onion and a homemade special sauce that’s also perfect for pairing with Old Bay fries on the side—and will elicit major “oohs” and “ahhs” from your dining companions.

Cooking Steps
• Adjust rack to top position and preheat oven to 425 degrees. Wash and dry produce. • Cut potatoes into 1⁄2-inch-thick wedges. Halve, peel, and thinly slice onion.
• Toss potatoes on a baking sheet with a drizzle of oil and half the Old Bay Seasoning (you’ll use more later). Season lightly with salt and pepper. TIP: No need to season generously—there’s already salt and pepper in the seasoning! • Roast on top rack until browned and crispy, 20-25 minutes.
• While potatoes roast, heat a large drizzle of oil in a medium, preferably nonstick, pan over medium-high heat. Add onion; cook, stirring occasionally, until browned and softened, 8-10 minutes. • Add 1 tsp sugar(2 tsp for 4 servings) and a splash of water; cook until onion is caramelized and jammy, 2-3 minutes more. Season with salt and pepper. • Turn off heat; transfer to a small bowl.
• Meanwhile, in a second small bowl, combine mayonnaise, ketchup, mustard, and as much remaining Old Bay Seasoning as you like. Set aside. • Form beef into two equal-size balls (four balls for 4 servings); season all over with salt and pepper.
• Heat a drizzle of oil in pan used for onion over medium-high heat. Once pan is hot, add beef. Firmly flatten each ball with a spatula to create very thin patties. (TIP: Do so carefully; oil may splatter a bit.) Cook to desired doneness, 3-4 minutes per side. (Don’t worry if the patties aren’t perfectly round—those irregular edges will turn crispy.) • In the last 1-2 minutes of cooking, top patties with cheddar; cover pan to melt cheese. Remove from heat.
• While patties cook, halve and toast buns. • Divide buns between plates and fill with patties, caramelized onion, and half the special sauce. Serve burgers with Old Bay fries on the side and remaining special sauce for dipping.
Ground Meat is fully cooked when internal temperature reaches 160°.

Reviews from our home cooks
Always a family favorite! This burger and the Sweet Thai Chili Burgers are the best! The meat is always fresh, the seasonings and sauces are perfect! We love asparagus! Very fresh, flavorful, with just the right amount of crunch. The Cheesy Smash Burger is 5 STARS!
I really enjoy the burgers! They're easy to cook and taste better when you're heavily spicing up the protein. I like to go heavy mixing in old bay with the protein, it comes out great! The potato's are easy prep too, I don't typically enjoy peeling anything. So far I've cooked burger-like items 3 times.
Oh my goodness! This was the best hamburger. It was moist, flavorful, and the sauce was delicious! I would buy this again! Yum!
These burgers are better than any burger from a restaurant. They taste so fresh. This order is on repeat. Easy meal for teens
Meat flavor with just sake and pepper was fantastic, as was sauce. Toll was really good, as was the sauce and cheese. Love these meals! Keep the quality!
Sauce and onions were just like being in a restaurant!
My family enjoyed this meal! it was easy to cook, but longer then expected.
Normally we love your potato buns, but for some reason this time they were way too thick, heavy and dry. Ruined the whole burger. Im hoping this was A once only thing, otherwise I'll stop getting the burgers.
Not much to say here. Solid burger option. A good burger is hard to top. This was a good burger.
Wonderful recipe. I just couldn't get the fries right for some reason. Not the recipe problem I think it was mine BUT overall it was amazing
