Why You’ll Love This Smashed Brussels Sprouts with Romesco Dipping Sauce Recipe

From the very first time I made this recipe, I was blown away by the depth of flavor. The Brussels sprouts get perfectly tender from boiling, then crispy on the outside after smashing and roasting, which creates such a fantastic contrast in textures. The Romesco sauce adds a vibrant punch of smoky roasted red peppers, toasted almonds, and a hint of spice that makes you want to dip every bite. It’s a flavor combination that feels both comforting and sophisticated.

What I really appreciate about this dish is how simple it is to prepare but still feels special enough for gatherings or holidays.

Plus, the recipe works for casual weeknight meals or side dish showstoppers when you have company. It definitely stands out on any table with its bright colors and bold flavors.

The ingredients for this recipe are incredibly simple yet essential to getting that perfect flavor and texture balance. Each plays a key role: from the hearty Brussels sprouts to the nutty almonds in the sauce, every element works together for a deliciously well-rounded dish.

Brussels sprouts: Choose fresh, firm sprouts about 2 pounds for great texture and flavor.
Extra virgin olive oil: Use high-quality olive oil for roasting and in the Romesco sauce to add richness.

Kosher salt: Essential for enhancing and balancing flavors throughout the dish.
Ground black pepper: Freshly ground adds subtle heat and aroma.
Roasted red peppers (12 oz jar): Provide the smoky sweetness base for the Romesco sauce.

Fire roasted tomatoes (14 oz can): Bring depth and a hint of acidity to the sauce.
Blanched almonds (1 cup): Give the Romesco sauce a lovely nutty creaminess.
Flat leaf parsley (1/3 cup, chopped): Adds fresh, herbal brightness to the sauce.

Garlic cloves (3): For savory pungency in the Romesco.
Lemon juice (1/2 lemon): The fresh acidity lifts the whole sauce.
Red wine vinegar (2 tsp): Adds a balanced tang to the Romesco.
Smoked paprika (1 tsp): Enhances the smoky flavor of the sauce with warmth.

Crushed red pepper flakes (1/2 tsp): Adds a gentle spicy kick that’s not overpowering.

Directions

Step 1: Begin by washing the Brussels sprouts thoroughly and trimming off their stems. Don’t worry if some outer leaves fall away — set those aside as you can roast them, too, for extra crispy bites.

Step 2: Bring a large pot of salted water to a rolling boil. Adding salt helps season the sprouts and enhances their natural flavor.

Step 3: Once boiling, add the Brussels sprouts to the pot and let them cook for about 15 minutes. You want them fork-tender but not mushy, so keep an eye on the timing.

Step 4: Prepare an ice bath while the sprouts cook. When the 15 minutes is up, drain the sprouts immediately and plunge them into the ice bath for 5 to 10 minutes to stop cooking and maintain their bright green color.

Step 5: After cooling, drain and dry the sprouts thoroughly—this is important to get a nice crisp when roasting.

Step 6: Preheat your oven to 450 degrees Fahrenheit and line a baking sheet with parchment paper for easy cleanup and even roasting.

Step 7: Arrange the Brussels sprouts evenly on the baking sheet. Then, using the back of a glass or a sturdy plate, gently smash each sprout until it’s roughly 1/2 inch thick. This increases their surface area for maximum crispness.

Step 8: Brush each smashed sprout generously with extra virgin olive oil, then sprinkle with kosher salt and freshly ground black pepper to taste. This step makes a huge impact on flavor and texture.

Step 9: Place the baking sheet in the oven and roast for 35 minutes, flipping the sprouts halfway through. You want them golden and crispy on both sides.

Step 10: While the sprouts roast, prepare the Romesco sauce by adding all sauce ingredients—roasted red peppers, fire roasted tomatoes, almonds, parsley, garlic, lemon juice, red wine vinegar, salt, smoked paprika, olive oil, and red pepper flakes—to a blender or food processor.

Step 11: Blend until the sauce is mostly smooth but still retains some texture. Taste and adjust seasoning as needed — sometimes I add a bit more lemon juice or smoked paprika for brightness.

Step 12: Once the Brussels sprouts are done roasting, transfer them to a serving dish. You can either drizzle the Romesco sauce over the top or serve it on the side as a dipping sauce. Serve immediately and enjoy the delicious contrast of crispy sprouts and smoky, creamy Romesco.

Servings and Timing

This recipe makes about 4 servings, perfect for sharing as a side dish or a snack. The prep time is roughly 15 minutes, mostly for washing and trimming the Brussels sprouts and prepping the sauce ingredients. Boiling takes 15 minutes followed by a 5 to 10-minute ice bath, then roasting for 35 minutes. Altogether, you’re looking at just over an hour from start to finish, including resting times to cool the sprouts. It’s totally worth it!

How to Serve This Smashed Brussels Sprouts with Romesco Dipping Sauce Recipe

A clear round food processor bowl sits on a white marbled surface filled with layers of ingredients: peeled white garlic cloves on the right mixed with green parsley leaves scattered on top, whole peeled red peppers laying flat under the parsley, and plenty of light beige blanched almonds covering the left side; some red spices sprinkled over the garlic and almonds add a pop of color. Surrounding the bowl are more ingredients on the white marbled surface, including a clear glass oil bottle with yellow oil at the top left, a garlic bulb with peeled cloves beside it, a small white bowl of blanched almonds, a small dish of ground black pepper, a wooden spoon with coarse salt in a shallow white bowl, a glass citrus juicer with a whole yellow lemon on top right, a small glass jar of crushed red pepper flakes with a wooden spoon inside, and an open tin of red peppers bottom right.

Whenever I serve this dish, it’s always a hit whether on a weeknight or at a festive gathering. I love pairing it with grilled chicken or roasted meats since the smoky sauce complements savory proteins beautifully. For a vegetarian meal, it goes well alongside a hearty grain bowl or a fresh salad with lemon vinaigrette to keep things bright and balanced.

Presentation-wise, I like to arrange the sprouts in a single layer on a large platter and either drizzle the Romesco sauce artfully over the top or provide a small bowl of the sauce for dipping. A sprinkle of extra chopped parsley or toasted almonds on top adds a lovely pop of color and texture. Serving these warm straight from the oven really brings out their full flavor and ensures the perfect crispy bite.

To drink, I often recommend a crisp white wine like Sauvignon Blanc or a light, refreshing beer. If you prefer non-alcoholic options, a sparkling water with lemon or a lightly brewed iced tea works wonders to cleanse the palate between bites. This recipe feels just right for family dinners, holiday spreads, casual get-togethers, or even just treating yourself on a weeknight when you want something deliciously different.

Variations

I love experimenting with variations on this recipe depending on what I have on hand or the flavors I’m craving. If you want a different nutty edge, swapping blanched almonds for toasted hazelnuts or walnuts in the Romesco adds a unique twist. For a nuttier or creamier sauce, sometimes I stir in a spoonful of almond butter or tahini.

If you have dietary restrictions, this dish is incredibly versatile. It’s naturally gluten-free and can easily be vegan by ensuring your olive oil is high quality and not blended with anything animal-based. For extra heat, I’ll add extra red pepper flakes or a dash of cayenne to the sauce. Alternatively, for a milder version, just reduce the spice to suit your taste.

For a change in cooking method, I’ve tried air frying the smashed sprouts which makes them super crispy in less time. You can also experiment with grilling the sprouts after smashing for a smokier flavor. The Romesco sauce itself can be served warm or at room temperature depending on your preference, which adds to the recipe’s adaptability.

Storage and Reheating

Storing Leftovers

If you happen to have leftovers (though that rarely lasts long in my house!), store the Brussels sprouts separately from the Romesco sauce in airtight containers. Keeping them separate helps preserve the sprouts’ texture and prevents the sauce from making them soggy. Stored properly in the fridge, the sprouts will keep well for up to 3 days, and the sauce for 4 to 5 days.

Freezing

While I don’t typically freeze this dish since roasted Brussels sprouts are best fresh, you can freeze the Romesco sauce on its own. I recommend storing the sauce in a freezer-safe container or ice cube trays for smaller portions. The sauce will keep well frozen for up to 3 months. When ready to use, thaw in the fridge and give it a good stir before serving.

Reheating

To reheat, I recommend warming the Brussels sprouts in a hot oven or air fryer for a few minutes to help re-crisp the edges. Avoid microwaving as it tends to make them soft and less flavorful. The Romesco sauce should be served at room temperature or gently warmed on the stove for a few minutes. Combine just before serving to keep the best texture and taste.

FAQs

Can I use frozen Brussels sprouts for this recipe?

Frozen Brussels sprouts can work in a pinch, but I highly recommend using fresh ones if possible. Fresh sprouts hold up better to boiling and smashing without becoming too mushy. If using frozen, thaw and dry them thoroughly before proceeding, and reduce boiling time slightly to avoid sogginess.

Is the Romesco sauce spicy?

The Romesco sauce has a gentle spicy kick thanks to the red pepper flakes, but it’s not overwhelmingly hot. You can easily adjust the level of heat by adding more or less crushed red pepper flakes according to your taste.

Can I make the Romesco sauce ahead of time?

Absolutely! The Romesco sauce actually benefits from sitting in the fridge for a few hours or overnight as the flavors meld beautifully. Just store it in an airtight container and give it a good stir before serving.

What else can I serve with these smashed Brussels sprouts?

These sprouts pair wonderfully with roasted meats, grilled chicken, or even a hearty grain salad. I also enjoy them as part of a tapas spread with olives, manchego cheese, and crusty bread.

How do I know when the sprouts are perfectly roasted?

You’ll want to see golden brown, crispy edges with tender centers. They should easily lift off the pan without sticking and have a toasted aroma. Flipping them halfway ensures even cooking and crispiness on both sides.
