Hashbrown Smash Burger with Maple Sausage and a Fried Egg Step-by-step instructions

Before you start

Take the ground beef and sausage out of the refrigerator while the griddle preheats, but no more than 30 minutes before cooking; cold fat smashes cleanly and sticks less.

Pat the frozen hashbrown patty dry on both sides with paper towels. Split the brioche English muffin and stage it near the stove, cut sides up.

Instructions

Blend, ball and stage

1. 1Blend the meat
   Combine the ground beef and the maple breakfast sausage meat in a mixing bowl. Work quickly with your fingertips until the two meats are just evenly streaked together, about 20 seconds. Do not knead or compress the mixture, since overworking it makes the smashed patties dense instead of tender.
   Look for The blend should look marbled, with pale sausage ribboned through the beef, and hold together loosely when pinched.
   Tip Chill the bowl in the freezer for 5 minutes first so the fat stays firm and the blend mixes cleanly.
2. 2Form the balls
   Divide the blend into 2 equal portions, about 4 oz each, and roll each one into a loose ball. Set them on a small plate without pressing them down. Keep the balls cold until the griddle is ripping hot; if the kitchen is warm, return them to the refrigerator for up to 30 minutes.
   Look for Each ball should hold its shape but show visible cracks and fat flecks on the surface.
   Tip Loose balls smash flatter and crust better than tightly packed ones, so resist the urge to compress them.
3. 3Set up the station
   Pat the hashbrown patty dry with paper towels so it crisps instead of steaming. Split the brioche English muffin and set both halves cut side up near the stove. Slice the American cheese, crack the egg into a small cup, and have the maple syrup within arm's reach.
   Look for Everything should be staged and reachable, because the cooking phase moves fast once the griddle is hot.
   Tip A dry hashbrown surface browns in half the time, so do not skip the paper towels.

At the end of this phase, the beef and sausage should be just streaked together, with no gray streaks of pure beef or pure sausage, and divided into two loose 4 oz balls that hold their shape without being compressed.

Smash, melt and fry

4. 4Heat the griddle
   Place a cast-iron griddle or heavy skillet over high heat and let it preheat for a full 5 minutes, until it reaches about 450°F (230°C). Flick a drop of water onto the surface; it should skitter and vanish instantly. A properly hot griddle is what builds the lacy, caramelized crust on smash patties.
   Look for The surface should look faintly shimmering, never smoking gray, and the water test should hiss and evaporate on contact.
   Tip Cast iron holds heat best for smashing; a thin pan will drop in temperature and steam the meat.
5. 5Smash the patties
   Set both meat balls on the hot griddle, spaced well apart, and immediately smash each one flat with the stiff spatula into thin disks about 4 inches wide. Cook undisturbed for 2 minutes so the underside develops a deep brown crust, pressing once halfway through.
   Look for The edges should look crisped and dark brown, with rendered fat pooling around each patty and no pink visible on top.
   Tip Smash once, hard, in the first 10 seconds; repeated pressing squeezes out juices and dries the patties.
6. 6Check doneness and melt the cheese
   Flip the patties, lay a slice of American cheese on each, and cook 1 minute more. Check the internal temperature with an instant-read thermometer: the patties are done at 160°F (71°C). Slide them onto a warm plate while you cook the egg, letting the cheese finish melting over the residual heat.
   Look for The cheese should slump and gloss over each patty, and the crust should stay audibly crisp when tapped with the spatula.
   Safe temperature 160°F (71°C) internal temperature (ground meat)
   Tip Ground meat must reach 160°F (71°C); the thermometer check takes two seconds and guarantees juicy, safe patties.
7. 7Fry the egg
   Melt the bacon fat in a small nonstick skillet over medium heat. Add the egg and fry until the whites are fully set and the edges turn lacy and frilled, 2 to 3 minutes. For a fully cooked yolk, continue until the yolk reaches 160°F (71°C); otherwise stop while the yolk still yields to the spoon.
   Look for The white should be opaque from edge to edge with crisp frilled lace around the rim, and the yolk should sit high and glossy.
   Safe temperature 160°F (71°C) internal temperature (egg dishes)
   Tip Bacon fat gives the egg its diner-style lace; tilt the pan and spoon hot fat over the white to set it faster.
8. 8Crisp the hashbrown
   While the egg fries, cook the hashbrown patty directly on the hot griddle or in a dry skillet over medium-high heat, about 3 minutes per side. Press it gently with the spatula to maximize contact. It is ready when both faces are deep golden and the surface crackles when pressed.
   Look for Listen for a dry, brittle crackle rather than a soft sizzle; the patty should feel rigid, not bendable, when lifted.
   Tip Start the hashbrown before the egg if your griddle runs crowded; it needs the most contact time to shatter crisply.

This is the phase to judge by sound and sight.

The patties should have emerged from their 2 undisturbed minutes with dark, lacy crusts and rendered fat pooling at the edges, and after flipping they should read 160°F (71°C) on a thermometer with cheese slumped and glossy on top.

Toast, stack and slice

9. 9Toast the brioche
   Set the split brioche English muffin cut side down on the warm griddle for 1 to 2 minutes, just long enough to pick up golden color and a thin layer of the rendered beef fat. A toasted surface keeps the crumb from turning sodden under the patties, cheese and yolk.
   Look for The cut face should be evenly golden with crisp edges, and the bottom should feel firm when pressed with a fingertip.
   Tip Toast briefly; brioche is rich and burns fast, so watch the last 30 seconds closely.
10. 10Build the stack
    Set the bottom brioche half on a plate and layer on the crispy hashbrown patty. Add both cheese-topped smash patties, then the fried egg. Drizzle the maple syrup over the egg, cap with the top brioche half, and press down very lightly so the yolk spreads through the stack.
    Look for The stack should sit tall but stable, with the egg lace visible at the edges and syrup just beginning to seep down the sides.
    Tip Hashbrown on the bottom acts as a crunchy, moisture-proof barrier that keeps the bread crisp to the last bite.
11. 11Slice and serve
    Cut the burger in half with a sharp serrated knife, straight down through the center, so the yolk breaks and runs into the cheese and hashbrown below. Serve immediately on a warm plate while every layer is still hot and the crunch is at its loudest.
    Look for The cross-section should show distinct layers: toasted crumb, golden hashbrown, crusted patty, melted cheese and glossy yolk.
    Tip A serrated knife saws gently; a straight blade can squash the stack and push the yolk out the sides.

The brioche faces should be evenly golden and firm to a light press, never pale or floppy. The stack, built from the bottom up as hashbrown, patties and cheese, egg, then maple drizzle and the top half, should stand tall and stable with the egg lace peeking out at the edges.

Common mistakes

The most common failure is a lukewarm griddle: below about 450°F (230°C), the patties gray out and steam instead of crust, and nothing can fix them afterward.

The second is overworking the meat blend; kneading it like meatloaf makes the patties springy, so mix for 20 seconds and stop.

How to tell it’s done

The patties are done when an instant-read thermometer reads 160°F (71°C) at the center, which at smash thickness takes about 3 minutes total; the crust should be deep mahogany and audibly crisp.

The hashbrown is done when both faces are golden and the patty feels rigid and brittle, not bendable.
