How To Cook Frozen Green Peas

Step 1 — Heat the oil. Warm olive oil in a medium saucepan over medium–medium-high heat.

Step 2 — Cook the onions. Add the minced onion, season with salt and pepper, and cook gently until the onions are soft and translucent but not browned.

Step 3 — Add the peas. Stir in the peas and cook for a few minutes, stirring frequently, so they heat through and combine with the onions.

Step 4 — Add liquid. Pour in enough water to just cover the peas and bring to a boil. Using broth is an easy flavor upgrade.

Frozen peas added to the onions and then water added and the peas simmering.

Step 5 — Simmer. Reduce heat to medium and simmer about 15–20 minutes, until the liquid has mostly reduced and the peas are tender.

Step 6 — Serve. Taste and adjust seasoning, then serve warm as a side.

Frequently Asked Questions

How long should I boil green peas?

Simmer frozen peas about 15–20 minutes until tender and most of the liquid has reduced.

Are frozen peas good for you?

Yes. Frozen peas are picked at peak ripeness and quickly frozen, which preserves nutrients and flavor.

How else can I season peas?

Try a squeeze of lemon to brighten flavors or a sprinkle of freshly grated Parmesan for richness. Fresh herbs like mint or parsley also pair well.

Tips For Making This Frozen Peas Side Dish

  • Cook onions low and slow: Soft, slightly sweet onions are the foundation of the best flavor.
  • Stir peas often at first: This helps them heat evenly and prevents sticking. Once you add water, occasional stirring is fine.
  • Leave a little liquid: A small amount of remaining liquid keeps the peas tender and saucy.
  • Use broth to boost flavor: Swap the water for vegetable or chicken broth for a simple upgrade.
  • Watch fresh peas: If using fresh, they will cook faster than frozen—check them earlier.
  • Prep ahead: Chop the onion in advance and store it in the fridge to save time.
  • Storage: Keep leftovers in an airtight container in the refrigerator up to 3 days. Reheat gently on the stovetop or in the microwave.
