Why This Roasted Brussels Sprouts Recipe Works Best

This seasonal side dish delivers a restaurant-quality sear by roasting sprouts undisturbed at high heat (450°F). The secret to its addictive flavor is the warm butter and Sherry Vinegar dressing. The acidity of the American Barrel Sherry Vinegar, cuts through the rich butter and umami-heavy anchovies, creating an emulsified glaze that clings to every leaf. It is the perfect acidic counterbalance for heavy proteins like steak, salmon, or roasted chicken.

As soon as "sweater weather" hits, Brussels sprouts take center stage. While many recipes rely on balsamic glazes, our Roasted Brussels Sprouts with Warm Butter Dressing uses Sherry Vinegar for a more sophisticated, nutty acidity. This dish isn't just for sprout lovers—the dressing is a versatile "cruciferous miracle" that works equally well with broccoli or cauliflower.

The Umami Foundation

The depth of this dish comes from an "invisible" ingredient: mashed anchovies. When whisked with melted butter and Dijon mustard, the anchovies disintegrate, providing a salty, savory backbone that complements the charred, nutty flavor of the roasted sprouts.

Ingredients That Matter

  • Fresh Brussels Sprouts: Look for firm, tight heads. Halving them allows for maximum surface area contact with the pan.
  • American Barrel California Sherry Vinegar: This barrel-aged vinegar provides a complex, toasted flavor profile that white or cider vinegars can't match.
  • Melted Butter & Dijon: These act as the emulsifiers, ensuring the dressing is thick enough to coat the vegetables without pooling at the bottom of the plate.

Steps for the Perfect Roast

  • The "No-Crowd" Rule: Arrange your sprouts face-down on a heavy steel baking sheet. Pro-Tip: Do not crowd the pan. If the sprouts are too close, they will steam rather than sear, losing that essential crispiness.
  • Undisturbed Roasting: Cook at 450°F for 15 minutes without flipping. This allows the bottom to develop a deep, caramelized crust while the outer leaves become airy and crisp.
  • The Anchovy "Disappearing Act": In your mixing bowl, use the back of a spoon to mash the anchovies into a paste before adding the liquid. They should be visually imperceptible in the final dressing.
  • The Allium Soak: If using minced shallots, soak them in the Sherry Vinegar for 5 minutes before mixing the rest of the dressing. This "quick-pickle" mellows the raw onion bite and infuses the vinegar with sweetness.

 

FAQs About Roasted Brussels Sprouts

Why are my roasted Brussels sprouts soggy?

Sogginess usually happens because the pan was overcrowded or the oven temperature was too low. Roasting at 450°F and giving the sprouts space ensures the moisture evaporates, leading to a crispy sear.

What is a good substitute for anchovies in the dressing?

If you want to avoid fish, use a teaspoon of white miso paste or a splash of soy sauce. Both provide the savory umami punch that makes the butter dressing so satisfying.

Can I make this recipe in an air fryer?

Yes. Air fry at 400°F for 10–12 minutes, shaking the basket halfway through. However, the oven method is preferred for the best "face-down" caramelization.

Side

This seasonal side dish is perfect for fall "sweater weather" and features fresh brussels sprouts roasted to a perfect sear. The warm dressing, made with melted butter and California Sherry Vinegar, provides a slight tang that cuts through the richness of meats like steak, chicken, or salmon. For those who aren't fans of sprouts, this savory, emulsified dressing also pairs beautifully with other cruciferous vegetables like broccoli or cauliflower.

Roasted Brussels Sprouts with Warm Butter & Vinegar Dressing

Ingredients

  • 1.5 lbs. of fresh brussels sprouts

  • ¼ teaspoon salt

  • 2 tablespoons of AVW Olive Oil

  • 2 anchovies, mashed

  • 2 tablespoons of butter, melted

  • 1 teaspoon of Dijon mustard

  • 2 tablespoons of AVW California Sherry Vinegar

  • Black pepper to taste

  • (optional) 2 tablespoons of shallots, minced

Directions

  1. Preheat oven to 450 degrees

  2. Trim and cut brussels sprouts in half

  3. Toss brussels sprouts with olive oil and salt and arrange them on a steel/heavy baking sheet face down.  For a better crisp/roast do not crowd the sheet (crowded brussels will steam)

  4. Cook undisturbed for 15 minutes to allow a sear on bottom and some crisped leaves on top

  5. While brussels cook: In a medium bowl (large enough to accommodate the brussels after roasting) use the back of a spoon or a fork to mash and disintegrate the anchovies as best as you can.  The goal is to blend them into the dressing (visually) imperceptibly.

  6. Optional:  If you are adding shallot to the dressing this is the time to mince the shallot and let it soak for a few minutes with the vinegar only in a separate small bowl. The addition of shallots gives more texture to the dish and a light allium flavor.  If you like an even stronger flavor skip the shallot and grate in a whole raw garlic clove—no extra texture but a bigger kick.

  7. Add vinegar (or the above vinegar/shallot mix), mustard, melted butter, and a few rounds of fresh ground black pepper to the mashed anchovies and whisk to emulsify. 

  8. Check that brussels are ready

  9. Mix brussels into emulsified dressing and gently toss

  10. Plate and serve right away.

  11. Note on Salt:  I have not added salt to the dressing because anchovies are usually pretty salty and I was using salted butter.  You will want to taste your dressing and adjust salt as needed.

  12. Note on Mixing Dressing:  The dressing as written should provide a good coating to the amount of brussels sprouts in the recipe.  I am dumping the brussels right into the dressing bowl simply to cut back on the number of dishes that need to be washed.  If you would like to meter the dressing used a bit more, I would have one small bowl for the dressing and then a medium bowl just for mixing the brussels and the dressing to the coating level you prefer.

  13. Note on (convenience) Pairing:  I like pairing this with oven roasted salmon.  Not just for the taste but because it lets me do it all in the oven at the same time.  Just salt well two salmon pieces (just enough for two portions) and let them cook in the oven for about as long as the brussels on their own baking sheet.  The salmon (especially Atlantic)  should be fat enough to cook without needing additional oil.  Super simple and an all-oven recipe with minimal clean-up (I put foil on the salmon baking sheet and cook it skin down—when I remove the salmon the skin sticks to the foil which then makes for easy toss and no clean action on the baking sheet…).  I like doing the brussels with direct contact to a baking sheet for a better sear.
