Cheesy Smashed Burgers
with Old Bay Broccoli, Caramelized Onion & Special Sauce
- Milk
- Eggs
- Soy
- Wheat
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 ½-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.

Review summary
Updated on Feb 2026- Flavor: The special sauce really made the burgers delicious! Some found Old Bay seasoning overwhelming; consider using less for milder taste.
- Ease of prep: Labor-intensive but worth it. For true smashburger texture, try making more, thinner patties from the provided meat.
- Suggestions: Add your own seasoning to the patties before cooking. Consider pairing with a green vegetable for a more balanced meal.
- Leftovers: Broccoli stays fresh for 1-2 days after delivery; use promptly for best results.
Reviews from our home cooks
This is really tasty. I recommend doubling the number of patties you make with the meat, so it is possible to get thin smashburger-like patties
Quite good tasting. Labor-intensive. Old Bay was overwhelming so I cut back on it.
Delicious! I was skeptical of the Old Bay fries but they were awesome!
American cheese....no need for white cheddar. Also, I think there should be an additional step in the instructions to wash the starch out of the potatoes as best you can.....and maybe some flour for the potatoes for a real crunch.
Good, but do wish for a green veg with the burger meals in addition to the fries.
Delicious burger. Felt weird not to have a vegetable of some kind. Potatoes are a starch.
I am tired of potato slices/french fries, wonder if another side like tater tots or onion rings could be a choice perhaps?
Some of the other burgers are more tasty...it was still good but left us feeling a little wanting more complex flavor...
Broccoli is fresh if used within a day or two of arrival; no longer
