Easy vegan frozen pea soup in a bowl topped with croutons.

This Frozen Pea Soup makes a quick and easy weeknight dinner. It's healthy, veggie-packed, and can be made at any time of year. Frozen peas make for a fresh and light tasting soup. It's a very different vibe than split pea soup—but in the most refreshing way possible.

It's no secret that we love frozen peas. They're inexpensive, nutritious, and keep for months. And, for most of the year, frozen peas are actually better than fresh. We use frozen peas in everything from Pesto Spinach Salad, Shepherd's Pie, Orzo Pasta Salad, and even Fried Rice.

You can garnish this soup with Croutons, fresh herbs, or Chili Lime Pepitas. Or, serve it just as is! You can't go wrong either way.

Ingredients to make vegan pea soup from frozen peas.

Frozen peas: Peas are an easy and inexpensive way to add veggies to your meal. They're a great source of plant-based protein, fiber, and vitamin C (USDA). And, a bag of peas can last up to 8 months in the freezer. Frozen peas are picked at peak season, then flash frozen. So, you can enjoy peas even in the depths of winter!
Potato: Makes the soup creamy, without dairy or extra added fat. Grating the potato helps it cook really fast. And it easily melds into a smooth soup once blended. We recommend a yellow potato, like Yukon Gold, because you don't need to peel its thin skin. Otherwise, a Russet or Red potato works too.
Vegetable broth: A good vegetable broth will make a big difference in this soup. Our favorite is a Vegan "Chicken" Bro th. But, a high-quality vegetable bouillon is delicious too. If you're not vegetarian, a regular chicken broth would work.
Thyme: This recipe keeps it simple with spices. You can use dried or fresh thyme. But, they're not a 1:1 substitute. Dried thyme is more potent than fresh thyme, so read the recipe card for exact measurements.
Baby spinach (optional): You can also add baby spinach to this frozen pea soup. It's a great way to pack in even more veggies. We tested versions with and without spinach. Both are delicious, so you can't go wrong!

Tips

Don't overcook the peas: Frozen peas have already been cooked (steamed). So, they're basically ready to eat. This recipe calls for cooking the peas just until they're hot (2 to 3 minutes). If you overcook them, they'll start to lose color and flavor.
Lemon for reheating: In our cookbook, we share a tip of adding a splash of acid to "wake up" leftovers. The same rule applies here. A squeeze of fresh lemon juice is delicious in leftover soup. Add after reheating for the brightest flavor. You don't need much...just a spoonful makes a difference!
Serve hot or cold: This truly is a year 'round soup. Frozen pea soup is delicious hot, of course! But, like our Vegan Potato Leek Soup, it's also great cold.
Garnishes take it over-the-top: This pea soup is delicious as is. But, you can make it even better with some pretty (and delicious) garnishes. Here we use crispy Air Fryer Croutons, olive oil, flaky salt, and fresh thyme. But, feel free to use what you have on hand. Roasted pumpkin seeds would be great too.
