For Assembly:
- 8 Hamburger Buns I prefer brioche
- 1 cup ish of garlic aioli (recipe is on webiste)
- optional extras: lettuce, tomato, onion, pickles, hot sauce, sliced jalapeño
Instructions
- In a large mixing bowl, combine ground beef, eggs, breadcrumbs, diced white onion, jalapeño, shallot, garlic, parsley, celery leaves, smoked paprika, garlic powder, salt, black pepper, white pepper, lemon juice, Dijon mustard, pickle juice, hot sauce, and BBQ sauce. Mix gently with hands until just combined—don't overwork to keep patties tender.
- Divide mixture into 8 equal portions and roll into balls. Set aside.
- For the mushroom topping: Heat avocado oil in a medium sauté pan over medium heat. Add julienned shallot and onion; cook 4–5 minutes until softened and starting to caramelize.
- Add butter and sage; let melt. Stir in sliced shiitake and baby bella mushrooms. Cook 5–7 minutes until mushrooms release liquid and brown.
- Add a splash of beef broth; scrape the bottom of the pan, simmer, and reduce until mushrooms are golden and saucy (3–5 minutes). Season with salt/pepper. Keep warm.
- Heat a large cast-iron skillet over medium-high heat with a drizzle of avocado oil.
- Place burger balls in the hot skillet (work in batches). Using a small plate or burger smasher, firmly smash each ball into a thin patty (about ¼-inch thick) right in the pan.
- Cook 1-2 minutes until edges crisp and brown. Flip, add 2 slices Swiss cheese per patty (or 1 if single), and cook 1 more minute until cheese melts and burger is cooked to medium (internal 140–145°F for juicy).
- While burgers cook, toast buns in oven at 425°F for 3–5 minutes or on skillet.
- Assemble: Spread garlic aioli on bottom bun. Layer onion-mushroom mix, cheesy smash patty (stack two for double if desired), more aioli, top bun.
- Serve hot with your favorite fry or cookout side – enjoy and remember it's okay to lick the plate!
Notes
Notes:
- Smash technique tip: Smash hard and fast – creates Maillard reaction for best crust. Don’t press after initial smash to retain juices.
- Make it healthier: Remove cheese and eat without a bun; add spinach or arugula for greens.
- Variations: Double-stack patties for classic smash style; add bacon for extra indulgence.
- Make-ahead: Prep patties and mushroom mix up to a day ahead (fridge). Cook fresh for the best texture.
- Storage: Refrigerate cooked patties/toppings up to 3 days; reheat gently in skillet. Freeze raw patties up to 3 months.
- Pairing idea: Serve with sweet potato fries, side salad, or grilled veggies for a balanced, nourishing meal.
