Roasted Pearl Onions

Pro tips

• Toss the onions halfway through roasting to ensure even caramelization and prevent sticking.
• Don't skip the butter—it helps the onions brown and adds richness to the final dish.
• Taste and adjust seasonings at the end; Old Bay and Creole seasoning are both salty, so go light and build up.
• Look for a deep golden-brown color on the onion surface as a doneness cue; they should be fork-tender inside.

Substitutions

• Butter → olive oil or ghee (flavor and fat will change slightly)
• Old Bay seasoning → paprika and cayenne (if you want a similar spiced flavor without Old Bay)
• Frozen pearl onions → fresh pearl onions, peeled (will require less roasting time, 15–18 minutes)

Storage & make-ahead

Store cooled roasted pearl onions in an airtight container in the refrigerator for up to 3 days; reheat gently in a 300°F oven.

Do I need to thaw frozen pearl onions before roasting?

No. Roast them straight from frozen. Add a few extra minutes to the cooking time if needed.

Can I make roasted pearl onions ahead of time?

Yes. Roast up to 2 days ahead, store in an airtight container in the refrigerator, and reheat gently in a 300°F oven for 5–10 minutes.

What temperature should I roast pearl onions at?

Roast at 400–425°F until the onions are golden brown and caramelized, about 20–25 minutes, stirring halfway through.

Can I scale this recipe?

Yes. Use the same ratio: 3 tablespoons butter per 10-ounce bag of frozen pearl onions, and adjust seasonings to taste.

What dishes pair well with roasted pearl onions?

They work as a side for roasted chicken, beef, pork, or fish. They also complement Thanksgiving and holiday dinners.
