From the MyKitchenBank Kitchen

Thick cauliflower slabs soak in a tangy pickle-brine buttermilk, get coated in pre-toasted panko, and bake on a wire rack until golden and shatteringly crisp. Piled on a buttery toasted bun with dill pickles and a creamy pickle sauce, they have all the crunch of a fried chicken sandwich with no deep-frying.

Equipment (8)

2 rimmed baking sheets, 18×13-inch (46×33 cm)
Wire cooling rack that fits inside one baking sheet
Large sharp chef's knife
Large skillet, 12-inch (30 cm)

Steps

Before you start

Choose 2 large, firm, tightly packed cauliflower heads (about 2 lb / 900 g each) with flat, wide centers. They give you the widest, sturdiest slabs.
Set aside 30 minutes for the buttermilk soak. Make the sauce and toast the panko while the cauliflower soaks.
You need a wire rack that fits inside a rimmed baking sheet. Without one, the bottoms turn soggy instead of crisp.
Place the oven racks in the upper and lower thirds, then preheat when the recipe tells you to.

1
Prep pans and ovenOven 425°F / 220°C
- Position oven racks in the upper and lower thirds and preheat to 425°F (220°C).
- Set the wire rack inside one baking sheet and brush the rack wires generously with the neutral oil so the coating doesn't stick.
- Leave the second baking sheet bare.

Ready when: Oven reads 425°F (220°C) and the rack wires are glossy with oil.
Tip: Give the oven at least 15 minutes to fully preheat while you prep; a hot oven is key to crisp panko.
2
Cut cauliflower slabs
- Stand one head stem-side down on a cutting board.
- Using a large knife, trim off a thin slice from each side to make the head a flat-sided block, then cut straight down through the stem to make two center slabs about ¾ inch (2 cm) thick.
- Repeat with the second head, giving 4 slabs total.
- Gently trim each slab so it's roughly bun-sized (about 4 inches / 10 cm across).
- Cut all remaining trimmings into bite-size florets and set aside.
+ Show details− Hide details
Ready when: You have 4 slabs about ¾ inch thick, each held together by a piece of core, and about 3 cups of loose florets.
Tip: Cut with firm, steady pressure straight through the core. If a slab crumbles, move it to the florets pile and cut another.
3
Soak in buttermilk
- In a shallow baking dish, whisk the buttermilk, 2 tablespoons pickle brine, 1 teaspoon hot sauce, garlic powder, and 1 teaspoon kosher salt.
- Nestle the 4 slabs into the mixture and spoon some over the tops.
- Let stand at room temperature for 30 minutes, flipping the slabs gently once halfway.

Ready when: Slabs are evenly coated in the buttermilk and look slightly glossy.
Tip: Do not soak longer than 1 hour; the acid begins to soften the cauliflower.
4
Mix the pickle sauce
- While the cauliflower soaks, stir together the mayonnaise, finely chopped pickles, 1 tablespoon pickle brine, Dijon, and the optional hot sauce in a small bowl.
- Taste and add a pinch of salt only if needed (pickles are already salty).
- Cover and refrigerate until serving.
+ Show details− Hide details
Ready when: Sauce is creamy, speckled with pickle, and tangy when tasted.
5
Toast the panko
- Heat a 12-inch (30 cm) skillet over medium heat for 1 minute.
- Add the panko, olive oil, and ¼ teaspoon salt.
- Stir constantly for 3–4 minutes.
- Tip into a wide shallow dish and spread out to cool.
+ Show details− Hide details
Ready when: Panko is pale golden, smells nutty, and looks dry and sandy rather than greasy.
Tip: Pre-toasting is what gives oven-baked panko its fried-looking color. Pull it off the heat when it's pale gold; it browns more in the oven.
6
Set up the station
- In a second shallow dish, whisk the flour, smoked paprika, black pepper, and ½ teaspoon salt.
- Arrange your station left to right: soaking slabs in buttermilk, seasoned flour, the buttermilk dish again for re-dipping, then toasted panko, then the oiled rack on the baking sheet.
+ Show details− Hide details
Ready when: Flour mixture is evenly orange-tinted with no lumps.
Tip: Keep one hand for wet ingredients and the other for dry to avoid clumpy fingers.
7
Coat the slabs
- Lift one slab from the buttermilk, letting excess drip off, then dredge in the flour mixture on both sides, patting off excess.
- Dip back into the buttermilk dish so it's completely wet, then press firmly into the panko, turning and packing crumbs on all sides and edges until fully covered.
- Place on the oiled rack.
- Repeat with the remaining slabs, leaving ½ inch (1 cm) between them.
+ Show details− Hide details
Ready when: No bare cauliflower shows through; the panko layer looks thick and evenly pressed on.
Tip: Press the panko on with your palm instead of just sprinkling it; pressed crumbs stay on after baking.
8
Season the florets
- Toss the reserved florets with the olive oil and ½ teaspoon salt directly on the bare baking sheet, spreading them in a single layer with space between them.
+ Show details− Hide details
Ready when: Florets are lightly glossy with oil and not touching.
9
Bake first sideOven 425°F / 220°C
- Slide the rack with the breaded slabs onto the upper oven rack and the florets onto the lower rack.
- Bake for 15 minutes without opening the door.
+ Show details− Hide details
Ready when: Panko on top is set and beginning to turn golden.
Tip: Don't spray extra oil on top; the toasted panko already has enough fat to brown.
10
Flip and finish bakingOven 425°F / 220°C
- Using a wide spatula, carefully flip each slab.
- Stir the florets and swap the two pans' positions.
- Bake another 13–15 minutes.
- Meanwhile, spread softened butter on the cut sides of the buns and toast them butter-side down in the empty skillet over medium heat for 1–2 minutes.
+ Show details− Hide details
Ready when: Slabs are deep golden brown and crunchy, a paring knife slides easily into the thickest part, and the bun faces are golden.
Tip: If the coating browns too fast but the center is still firm, tent the slabs loosely with foil and bake 5 more minutes.
11
Rest and assemble
- Let the slabs rest on the rack for 3 minutes so the coating firms up.
- Spread pickle sauce on both toasted bun halves.
- Layer a lettuce leaf on each bottom bun, then a cauliflower slab, then 4 pickle chips.
- Add the top bun and serve right away with the roasted florets alongside.

Ready when: Coating crackles when tapped and the burger stacks neatly.
Tip: Assemble just before eating; the crust softens within about 10 minutes once sauced.

Good to know

Tips

Flat, wide center slabs hold together best. If a slab breaks, bread the pieces together and press them tightly into a patty shape before baking.
Always bake on an oiled wire rack so hot air circulates underneath; a flat pan traps steam and softens the bottom crust.
Pat pickle chips dry on a paper towel before stacking so they don't make the crust soggy.
For a spicier burger, add 1 tablespoon hot sauce to the buttermilk soak or a pinch of cayenne to the flour.

Make ahead

Slice the cauliflower and make the pickle sauce up to 1 day ahead; refrigerate the slabs in a covered container (without buttermilk) and the sauce in a sealed jar. Soak, coat, and bake the day you serve.

Storage & reheating

Best eaten fresh. Store leftover slabs (without buns or sauce) in an airtight container in the refrigerator for up to 3 days. Reheat on a wire rack on a baking sheet at 400°F (200°C) for 10–12 minutes until hot and crisp; the microwave makes them soggy. Baked slabs can be frozen on a tray, then bagged, for up to 1 month and reheated from frozen at 400°F (200°C) for 18–20 minutes. Pickle sauce keeps in the fridge for up to 5 days. Room temperature: no more than 2 hours.

Substitutions

buttermilk → Whole milk plus lemon juice or white vinegar. Stir 1 tbsp acid into 1¼ cups (300 ml) milk and let it sit 5 minutes before using.
panko breadcrumbs → Crushed cornflakes or gluten-free panko. Use the same weight; skip the extra salt if the cornflakes are salted.
all-purpose flour → Gluten-free 1:1 flour blend. Use with gluten-free panko and buns for a fully gluten-free burger.
mayonnaise → Plain Greek yogurt or vegan mayonnaise. Yogurt makes a tangier, lighter sauce; vegan mayo makes the whole burger dairy-free if you also use a plant-based buttermilk.
