Lemon Parmesan Roasted Sugar Snap Peas

Lemon Parmesan Roasted Sugar Snap Peas turn a simple green vegetable into the kind of side dish people keep reaching for. The peas roast quickly at high heat, so their edges blister while the centers stay sweet and crisp. Red onion softens alongside them, adding a mellow bite and a beautiful pop of color.

A warm lemon-Dijon butter goes on after roasting, which keeps the citrus bright and helps the Parmesan cling to every pod. Fresh parsley adds a clean finish, while a small pinch of red pepper brings gentle warmth without making the dish spicy. The whole recipe is ready in about 20 minutes and works beautifully beside salmon, chicken, steak, or spring pasta. It is easy enough for a weeknight yet polished enough for a holiday table. Best of all, the snap peas still taste like snap peas—just brighter, richer, and much harder to leave alone.

Recipe Yield: 4 servings

INGREDIENTS

1 lb sugar snap peas, strings removed and thoroughly dried
1/2 small red onion, cut into 1/4-inch wedges and separated
1 tbsp unsalted butter, melted
1 tsp finely grated lemon zest
2 tsp fresh lemon juice
1/2 tsp Dijon mustard
1/3 cup finely grated Parmesan cheese, divided
1 tbsp olive oil
1/2 tsp kosher salt
1/2 tsp garlic powder
1/4 tsp black pepper
1/8 tsp crushed red pepper flakes
2 tbsp chopped fresh parsley

INSTRUCTIONS

1. Preheat the pan:
Place a large rimmed sheet pan in the oven. Then, preheat the oven to 450°F.

2. Season the vegetables:
Toss the sugar snap peas and red onion with olive oil, salt, garlic powder, black pepper, and red pepper flakes.

3. Roast until blistered:
Carefully spread the vegetables across the hot pan in one layer. Roast for 6 minutes, toss, and continue roasting for 4 to 6 minutes until browned in spots but still crisp-tender.

4. Prepare the lemon butter:
Meanwhile, whisk the melted butter, lemon zest, lemon juice, and Dijon until smooth.

5. Finish and serve:
Transfer the hot vegetables to a serving bowl. Toss with the lemon butter, half the Parmesan, and parsley. Sprinkle with the remaining Parmesan and serve immediately.

HELPFUL TIPS TO PERFECT THIS RECIPE

• Dry the sugar snap peas thoroughly: Surface moisture creates steam and prevents the peas from developing lightly blistered, caramelized spots.
• Keep everything in one loose layer: A large sheet pan gives the peas and onions enough room to roast instead of becoming soft or watery.
• Watch the final two minutes: Snap peas vary in size, and ovens brown differently. Remove them while they still have a juicy, crisp-tender bite.
• Finish just before serving: Tossing the vegetables with lemon butter and Parmesan while hot creates the best coating. However, serve promptly so the peas stay crisp.
