If you’re a lover of peas, you’ve got to try this recipe. Sheet pan roasted peas with garlic and onion is a quick-fix, no-fuss side dish that you can pull together with just 6 ingredients and 10 minutes of effort. It’s good enough to serve to your meat loving friends and family at a dinner party or add to your Thanksgiving dinner table. Get ready for rave reviews!


  • 1 bag (16 oz) of frozen peas (regular peas, not petit)
  • 1 head of garlic cloves, peeled
  • 1 yellow onion, cut into thin slices or thick chunks (to cut into thick chunks, slice in half through the root, slice off the both ends, and then slice each half into quarters like you would an apple)
  • ½ teaspoon of salt
  • ¼ teaspoon of black pepper
  • 4 tablespoons of plant-based butter


  1. Preheat your oven to 425° F. 
  2. On a full sized baking sheet, add the frozen peas, garlic cloves, onion slices, salt, and pepper. 
  3. In a small ramekin, add 4 tablespoons of vegan butter and heat in a microwave just until melted.
  4. Drizzle the melted butter over the  sheet pan and mix everything together immediately until evenly coated. The butter will start to harden around the  frozen peas—that’s ok!
  5. Bake for 10 minutes. Remove from the oven, toss and mix everything, and pop it back in the oven for another 10 minutes, until the onion just starts to brown at the corners. Enjoy immediately!
