Sweet and Spicy Roasted Nuts with Maple and Cinnamon

These Spiced Nuts are inspired by the iconic Union Square Café bar nuts — the perfect cocktail snack. Warm, buttery roasted nuts are tossed with fresh rosemary, a touch of brown sugar, and a hint of cayenne for gentle heat. The result is a balanced mix of sweet, salty, and savory flavors that’s utterly addictive.

Ideal for parties, homemade gifts, or simply snacking straight from the tray, this elegant recipe is quick to make and always impresses.

Why This Recipe Is So Delicious

Warm, buttery coating: Each nut is coated in a fragrant rosemary butter that enhances the nuts’ natural richness.
Savory + sweet + a touch of heat: Brown sugar and cayenne create a craveable contrast that keeps you reaching for more.
Fast and simple: From start to finish in about 20 minutes — no complicated steps or special equipment.
Crowd-pleaser: A classic choice for cocktail hour, holiday gatherings, and gift jars.

Before You Begin

Use fresh rosemary for the best aroma and flavor — dried just can’t replicate the bright herbal notes. Lightly toasting the nuts first unlocks their oils and deepens their flavor. If your nuts are already salted, reduce or omit the added salt to taste. Dark brown sugar adds richer molasses notes, but light brown sugar works well too. Toss the warm toasted nuts in the butter mixture while still warm so the coating adheres properly.

Ingredients for Spiced Nuts

Below is a practical ingredient overview. Exact measurements and the recipe steps follow further down.

Roasted nut mix: Use a reduced-salt roasted assortment so you can control the seasoning. Classic choices include almonds, cashews, pecans, and hazelnuts; pistachios also make a lovely addition.
Fresh rosemary: Finely chopped — this is central to the recipe’s character.
Cayenne pepper: For gentle heat; adjust to taste.
Brown sugar: Packed; dark or light brown sugar both work.
Salt: Add sparingly if nuts are already salted.
Unsalted butter: Melted; the base for the flavored coating.

Pro Tips

Toast evenly: Spread nuts in a single layer and stir once during baking so they brown uniformly. Customize the mix: Stick to classic choices (almonds, cashews, pecans, hazelnuts) or add pistachios for color and flavor. Serving suggestion: Serve warm in a bowl alongside cocktails, or sprinkle over a salad for added crunch. Gift idea: Once cooled, portion the nuts into small mason jars tied with twine for a simple hostess gift.

In a large bowl, combine the finely chopped fresh rosemary, cayenne pepper, brown sugar, salt (if using), and melted unsalted butter. Add the warm toasted nuts and toss thoroughly so each nut is evenly coated. Serve warm or at room temperature.
