Green peas? Yes, please! There’s just something about a shimmering sheet pan of roasted peas that is so satisfying and also super fun. It’s hard to resist doing a bit of rocking and rolling while they’re still resting on the tray.

This vegan sheet pan recipe is incredibly simple to make and handy to have in mind for when you’re clearing the fridge of veggies on the verge of freezer burn. Although you can always use frozen corn, green beans, broccoli, or other veggies, green peas are practically perfect for this preparation.

Above all, treat your plumpish peas with tender loving care, and let’s get ready to roast!

Ingredients Needed

This recipe is one you’ll want to return to time and time again because it’s so simple and quick to throw together. Just 6 ingredients are needed for a truly flavorful and delicious side dish!

Sheet Pan Recipe Roasted Peas Ingredients Flatlay
  • Frozen peas: Use regular frozen peas, not petite peas, for this recipe. Regular peas have a slightly firmer texture that holds up better during roasting. No need to thaw the peas before roasting!
  • Yellow onion: You can slice the onion into thin slices or thick chunks depending on your preference. Thick chunks will become tender and caramelized, adding a rich, sweet note. Thin slices will crisp up and add a different texture.
  • Garlic: Use whole cloves or garlic, peeled. Roasting mellows the garlic’s pungency, adding a mild, sweet flavor to the roasted peas.
  • Dairy-free butter: Adds richness and helps achieve a golden, caramelized finish on the peas and onion. For anyone who is trying to stick to a low-fat diet or just ran out of their last stick of vegan butter, you can make your own vegan butter, or use your favorite oil instead, such as olive, vegetable, coconut, or avocado. Balsamic vinegar is also a great option that adds a ton of flavor.

Roasted Peas Variations

The best thing about a pan of roasted peas is that they go well with almost anything. The value of a little legume with every dish is truly priceless because they provide protein, fiber, and essential nutrients that we need each day. To make the most out of this simple side meal, try out these tempting tips:

  • Peas in a Pod – Swap frozen peas for sugar snaps, snow peas, or string beans. You’ll add extra fiber, more texture, and a whole new look to this really quick recipe.
  • Shake Up the Spices – Garlic and onion are classic seasonings for this inviting entrée, but you can always switch them up. Use basil and oregano for a more Italian-inspired dish or ginger and scallions for an Asian flair. Feeling bold? Brush a bit of wasabi on your peas and be brave enough to eat them!
  • Pile on the Peppers – Whether hot or mild, feel free to bulk up the dish with a bold or bell pepper. Slice thinly and mix in with the pretty peas. Use red, orange, or yellow peppers to add some extra color.
  • Remember the Rainbow – Speaking of extra color, food is far more attractive when it’s more than one color. Consider adding in diced orange carrots, red peppers, purple onions, yellow corn kernels, or even finely chopped blue potatoes to make the dish more festive. Zucchini and squash are also great additions. Here’s how to roast zucchini and squash. During the holiday season, bright red dried cranberries look amazing along with the jolly green peas.

How To Make Roasted Peas

The step-by-step process couldn’t get any easier. Simple dump, mix, and roast!

Step 1: Preheat your oven to 425°F.

Step 2: On a full-sized baking sheet, add the frozen peas, garlic cloves, onion slices, salt, and pepper. Melt 4 tablespoons of vegan butter in a small ramekin in the microwave.

Step 3: Drizzle the melted butter over the vegetables on the baking sheet and mix immediately to coat everything evenly. It’s fine if the butter begins to harden on the frozen peas.

Step 4: Bake for 10 minutes, then remove from the oven and toss everything together. Return to the oven for another 10 minutes, or until the onions start to brown at the edges. Enjoy immediately!

Top Tips

  • Use Frozen Peas Directly: There’s no need to thaw the peas before roasting. Using them straight from the freezer helps them retain their shape and texture during cooking.
  • Even Coating: Ensure that the peas, garlic, and onions are evenly coated with melted butter, salt, and pepper.
  • Toss Halfway: Stirring the mixture halfway through cooking ensures even roasting and prevents any sticking to the pan.

What To Serve With Roasted Peas

Roasted peas are a versatile side dish that pairs well with a variety of meals. Here are some of my favorite ways to serve it up:

Frequently Asked Questions

Are green peas good for you?

Besides being really cute and easy to eat (and grow!), peas are such powerhouses of protein and health benefits. For only ½ cup, there are 4 grams each of protein and fiber. Forget the fiber supplements! Just eat plenty of peas. Besides being high in vitamins A, K, and C, green peas are also rich in minerals like thiamine, folate, manganese, iron, and phosphorous.

Which peas can you roast?

While this recipe calls for frozen peas, you can actually roast canned peas as well! Just know that they will need to be drained first, and will roast faster than frozen peas.

Simple Storage

While they’re best fresh out of the oven, storing your leftover roasted peas is easy-peasy! Place an extras in a covered container and they’ll keep fresh in the fridge for up to 3 days. To reheat, just throw them in the microwave for a minute or two or do a quick sauté in a saucepan over medium heat until desired temperature.

Freezing is also a great option, if you’ve made a bunch beforehand. You’ll be pleased to know that your peas will stay fresh for up to eight months. Place the container in the refrigerator overnight to thaw when ready to eat.
