Ingredients
The star of this recipe is fresh Brussels sprouts, chosen for their tight, glossy heads that hold up well to the smash technique. A touch of olive oil and sea salt helps develop that coveted caramelized crust, while the garlic aioli brings a creamy, aromatic finish. Simple pantry staples like lemon juice and Dijon mustard brighten the sauce, and a pinch of smoked paprika adds a subtle smoky undertone that elevates the whole dish.
Main Ingredients
- 1 lb (450 g) Brussels sprouts, trimmed
- 2 Tbsp extra‑virgin olive oil
- ½ tsp sea salt (plus more for seasoning)
Garlic Aioli
- ½ cup mayonnaise
- 2 cloves garlic, finely minced
- 1 tsp Dijon mustard
- 1 tsp freshly squeezed lemon juice
- ¼ tsp smoked paprika
- Pinch of black pepper
Seasonings & Garnish
- ¼ tsp flaky sea salt (for finishing)
- Fresh parsley, chopped (optional garnish)
Together, these ingredients create a balanced symphony of flavor and texture. The olive oil and salt coax the sprouts into a deep, caramelized hue, while the lemon‑brightened aioli adds a tangy, creamy counterpoint. Smoked paprika weaves a whisper of earthiness throughout, and the final sprinkle of flaky sea salt amplifies every bite. The result is a dish that’s crunchy, creamy, and irresistibly savory.
Step-by-Step Instructions
Preparing the Sprouts
Begin by rinsing the Brussels sprouts under cold water, then trim the stems and remove any outer leaves that look wilted. Cut each sprout in half lengthwise; this creates a flat surface that will later be smashed for maximum caramelization. Place the halves in a large pot of salted boiling water and blanch for 3‑4 minutes, just until they turn bright green. Drain and immediately transfer to an ice‑water bath to halt cooking and preserve color.
Smashing & Seasoning
Pat the blanched sprouts dry with a clean kitchen towel. Arrange them on a sturdy cutting board, flat side down. Using the heel of your hand or the bottom of a sturdy skillet, press each sprout firmly until it cracks and flattens—don’t pulverize it; you want a large surface area. Transfer the smashed sprouts to a large mixing bowl, drizzle with 2 Tbsp extra‑virgin olive oil and sprinkle with ½ tsp sea salt. Toss gently to coat evenly.
Roasting to Perfection
- Preheat the oven. Set your oven to 425°F (220°C) and line a baking sheet with parchment paper. A hot oven ensures the sprouts develop a deep, caramelized crust without steaming.
- Arrange the sprouts. Spread the smashed sprouts in a single layer, skin side down, on the prepared sheet. Overcrowding traps moisture, so use two sheets if necessary.
- Roast. Bake for 20‑25 minutes, turning once halfway through. Look for edges that are golden‑brown and slightly crisp—this is the visual cue that they’re done.
- Finish with flaky salt. Immediately after removing from the oven, sprinkle ¼ tsp flaky sea salt over the hot sprouts for an extra pop of flavor.
Making the Garlic Aioli
While the sprouts roast, combine ½ cup mayonnaise, minced 2 cloves garlic, 1 tsp Dijon mustard, 1 tsp lemon juice, ¼ tsp smoked paprika, and a pinch of black pepper in a small bowl. Whisk until smooth; the garlic will mellow slightly, creating a creamy, fragrant sauce that’s ready to drizzle the moment the sprouts emerge from the oven.
Plating & Serving
Transfer the roasted sprouts to a serving platter. Drizzle generous spoonfuls of the garlic aioli over the top, allowing it to pool in the crevices. Garnish with a scatter of chopped fresh parsley for color and a final dash of flaky sea salt if desired. Serve immediately while the sprouts are still crisp and the aioli is cool, creating a delightful temperature contrast.
Tips & Tricks
Perfecting the Recipe
Dry Thoroughly. After blanching, pat the sprouts completely dry. Moisture will steam them, preventing the coveted crispy edges.
Uniform Smashes. Aim for a consistent thickness—about ¼‑inch thick—so every piece browns evenly.
Use High Heat. A hot oven (425°F) creates rapid caramelization without drying the interior.
Rest Before Serving. Let the sprouts sit for 2‑3 minutes after drizzling the aioli; this allows the sauce to settle into the crevices.
Flavor Enhancements
Add a splash of aged balsamic reduction just before serving for a sweet‑tangy glaze. A pinch of crushed red pepper flakes in the aioli introduces subtle heat. For extra richness, whisk in a teaspoon of melted butter into the aioli right before drizzling.
Common Mistakes to Avoid
Skipping the blanch step leaves the cores tough and unevenly cooked. Over‑crowding the baking sheet causes steaming, resulting in soggy sprouts. Also, avoid using too much oil; excess oil will make the sprouts greasy rather than crisp.
Pro Tips
Invest in a Good Knife. A sharp chef’s knife makes trimming and halving the sprouts quick and clean, preserving their shape.
Use a Cast‑Iron Skillet for Smashing. The heavy bottom distributes pressure evenly, giving a consistent flatten without crushing the sprout.
Make Aioli Ahead. Prepare the garlic aioli up to 12 hours in advance; the flavors meld and intensify.
Finish with Fresh Herbs. A sprinkle of chopped parsley or chives just before serving adds brightness and visual appeal.
Variations
Ingredient Swaps
Swap Brussels sprouts for mini cauliflower florets or kale chips for a different texture. Replace the garlic aioli with a lemon‑tahini drizzle for a nutty, dairy‑free alternative. If you enjoy spice, incorporate a teaspoon of harissa paste into the aioli for a North‑African twist.
Dietary Adjustments
For a vegan version, use a plant‑based mayo (such as aquafaba or soy mayo) in the aioli and skip the butter garnish. Gluten‑free diners need only ensure any packaged seasoning is certified gluten‑free. To keep it keto, omit the honey (if used in a variation) and rely on the natural sweetness of the sprouts.
Serving Suggestions
Pair these crispy sprouts with a crisp white wine like Sauvignon Blanc or a light lager. They also shine alongside a quinoa salad tossed with citrus vinaigrette, or as a topping for loaded baked potatoes. For a party platter, arrange them on a wooden board with assorted dips and charcuterie.
Storage Info
Leftover Storage
Allow the sprouts and aioli to cool completely, then transfer each component to separate airtight containers. Store the sprouts in the refrigerator for up to 3 days; the aioli will keep for 5 days. For longer preservation, freeze the roasted sprouts (without aioli) in a freezer‑safe bag for up to 2 months—thaw before reheating.
Reheating Instructions
Reheat the sprouts in a preheated 350°F oven for 10‑12 minutes, uncovered, to revive the crispness. If you’re short on time, a quick skillet toss over medium heat works, adding a splash of olive oil. Warm the aioli gently in a microwave (15‑20 seconds) or at room temperature; never overheat, or it will separate.
