If there’s one side dish that has the power to convert even the most stubborn Brussels-sprout skeptic, it’s this one. Picture this: tender sprouts smashed until their edges fray into lacy, caramelized crunch, studded with smoky bacon that’s rendered just enough to infuse every bite with its salty, porky essence. The first time I served these at a Friends-giving potluck, the platter came back to the kitchen scraped clean—save for a single sprout that my cousin claimed was “too pretty to eat” (she ate it anyway).
I developed this recipe after years of roasting Brussels sprouts only to wish they were crispier. Smashing them post-steam creates craggy surfaces that seize into golden shards in a ripping-hot oven. Add bacon fat—liquid gold, really—and you’ve got a side that eats like a steakhouse appetizer. They’re perfect beside a holiday rib roast, weeknight pork chops, or even cold, straight from the fridge, standing in the glow of the refrigerator light. Make them once and you’ll find yourself buying Brussels sprouts on purpose, not just because they’re on sale and you feel virtuous.
Why This Recipe Works
- Steam-then-smash: A quick microwave steam softens the cores so you can flatten without crumbling, yielding fluffy interiors and shatter-crisp edges.
- Bacon fat basting: Rendering the bacon first gives you free flavor oil; brushing it over the sprouts ensures every leaf is seasoned.
- Two-temperature roast: Starting at 475 °F for color, then dropping to 425 °F, prevents bitter char while maximizing crunch.
- Cast-iron magic: A pre-heated skillet acts like a griddle, searing the bottoms while the tops blister.
- Make-ahead friendly: Steam and smash up to 24 h ahead; hold on a parchment-lined sheet for pop-in-the-oven ease.
- Umami bomb finish: A whisper of maple syrup and soy in the final minutes glazes the bacon, balancing the sprouts’ natural bitterness.
Ingredients You'll Need
Great sprouts start at the store. Look for bright-green, tightly furled heads that feel heavy for their size; yellowing outer leaves or a sulfurous smell signal age. Smaller sprouts (about 1–1¼ inches) are sweeter and crisp up faster—ideal here. Buy them on the stalk if you can; they stay perky for weeks in the crisper.
Brussels sprouts – 1½ lb (about 24 small). Peel off any ratty outer leaves; save them—they roast into crunchy chips. If only large sprouts are available, halve them before steaming.
Thick-cut bacon – 6 oz (about 5 slices). Thick cut renders slowly, giving you time to collect the fat and leaving meaty shards that won’t vanish in the oven. Pepper bacon adds a lovely bite; applewood is subtly sweet.
Olive oil – 2 Tbsp. Used to loosen the bacon fat so it brushes on smoothly. Choose a mild, fruity oil; extra-virgin is fine, but skip the grassy, peppery finishing oils.
Maple syrup – 1 Tbsp. A quarter-turn toward the end lacquers the bacon and encourages lacquer-like edges. Grade B (now called Grade A Dark) has deeper flavor.
Soy sauce – 1 tsp. Provides stealth umami; use tamari for gluten-free.
Garlic powder – ½ tsp. Granulated disperses without burning like fresh garlic can at high heat.
Smoked paprika – ¼ tsp. Echoes the bacon’s smoke and tints the sprouts a burnished red.
Kosher salt & freshly ground black pepper – Season at every layer; the coarse crystals adhere better than table salt.
Optional finish: Lemon zest, shaved Parmesan, or a drizzle of balsamic reduction for flair.
How to Make Crispy Smashed Brussels Sprouts With Bacon For A Flavorful Side
Prep the steamer
Place a microwave-safe steamer basket in a large bowl with ¼ cup water. Add sprouts, cover tightly with plastic wrap, and microwave on high 4 minutes (for 1-inch sprouts) or 5 minutes if larger. They should yield to a knife tip but still feel firm. Transfer to an ice-water bath for 30 seconds to halt cooking, then drain and pat very dry. Moisture is the enemy of crisp.
Preheat oven & skillet
Set a 12-inch cast-iron skillet (or heavy baking sheet) on the middle rack and heat oven to 475 °F. A screaming-hot vessel jump-starts the Maillard reaction on the cut faces.
Render the bacon
While the oven heats, cut bacon crosswise into ½-inch lardons. In a cold skillet on medium, cook until fat renders and edges caramelize, 6–7 minutes. Lower heat if browning too fast. Transfer bacon to a paper-towel-lined plate; reserve 2 Tbsp fat.
Smash time
On a cutting board, place a sprout cut-side down. Use the bottom of a heavy drinking glass or a small skillet to press until it flattens to about ½-inch thick; petals will splay. Repeat. The goal is maximal surface area without pulverizing the core.
Season & coat
Whisk reserved bacon fat with olive oil, maple, soy, garlic powder, smoked paprika, ½ tsp kosher salt, and ¼ tsp pepper. Brush or drizzle over smashed sprouts, both sides.
Sear in the hot pan
Carefully remove the pre-heated skillet. Arrange sprouts cut-side down; listen for the sizzle. Roast 8 minutes without moving. Slide bacon bits between sprouts.
Drop temp & finish
Reduce oven to 425 °F. Flip sprouts with a thin metal spatula, scraping the crisp bits with them. Roast another 8–10 minutes until edges are deep mahogany.
Final glaze
Drizzle remaining maple-soy mixture over everything, toss quickly, and roast 2 final minutes so the syrup bubbles but doesn’t burn. Finish with a shower of lemon zest for lift.
Expert Tips
Dry = crisp
After the ice bath, roll sprouts in a lint-free towel; centrifugal force flings water outward. Even a drop of residual steam will soften crust.
Thermal shock trick
Placing cold sprouts on a hot pan can crack the seasoning. Let them come to room temp 10 minutes while the oven heats.
Glass vs. mug
A flat-bottomed glass gives even pressure; a mug handle can torque and snap cores. If sprouts are tiny, use a wide-mouth jar.
Batch smart
Over-crowding steams instead of roasting. If doubling, use two pans on separate racks; swap positions halfway.
Finishing salt
A pinch of flaky Maldon right out of the oven adds pops of salinity and visual sparkle.
Air-fryer hack
Cook bacon in the basket at 375 °F for 6 minutes. Toss in sprouts, 400 °F 7 minutes, shake, 400 °F 5 more. Faster, smaller cleanup.
Variations to Try
-
Korean twist
Sub gochujang for maple, add sesame seeds and scallions at the end. Bacon stays.
-
Vegetarian
Swap bacon for smoked almonds; toast ¼ cup slivered almonds in 2 Tbsp brown butter, toss through at the end.
-
Holiday sparkle
Add ⅓ cup dried cranberries during the last 2 minutes; they puff slightly and provide tart contrast.
-
Cheese lover
Sprinkle ¼ cup finely grated aged gouda in the final minute; it melts into wispy frico.
-
Low-sugar
Omit maple; instead whisk 1 tsp balsamic glaze with the soy for sheen minus sugar.
-
Spicy
Stir ⅛ tsp cayenne into the fat; finish with a squeeze of lime and cilantro.
Storage Tips
Make-ahead: Steam, smash, and refrigerate on a parchment-lined sheet up to 24 hours. Cover loosely with foil; condensation softens crust. To revive, let stand at room temp 15 min, brush again with melted bacon fat, roast as directed.
Leftovers: Cool completely, then store in an airtight container up to 4 days. Reheat in a 425 °F oven or air-fryer 4–5 minutes; microwaves turn them rubbery.
Freezer: Freeze roasted sprouts (without bacon) in a single layer on a sheet, then bag up to 2 months. Reheat from frozen 12 minutes at 425 °F; add freshly cooked bacon bits.
