Why You’ll Love this Easy Mashed Peas Recipe with Roasted Vegetables!

This mushy peas recipe is a great way to get your veggies in! Peas are a solid source of plant protein, so a new way to enjoy them is always a win for me. The sweetness of the peas and onions makes it super tasty and delicious, and it’s so quick to prepare. Roast your veggies in the oven with some olive oil while you boil the peas, mash the peas, then serve them together. Voilá! You have a perfect weekday lunch!
The bright colors, from vibrant green pees to oranges and purples of roasted veggies, makes it so fun to eat and appealing to kids and adults alike. And if you’re not usually a fan of cauliflower this is a great way to eat it. Roasting it in the oven makes the flavor get to a whole new level. Nutty and sweet. Just perfect!
If you want to add an extra touch to it you could make a simple vegan alfredo sauce or garlic cream sauce and drizzle it on top or maybe toast some baguette slices and put them on the side. So good!
What are Mashed Peas?
This bright green, nutrient dense side dish goes by the name mashed peas, mushy peas, or smashed peas. It might sound like an unusual recipe, but let me tell you – they’re so yummy! Don’t let potatoes get all the credit for being yummy when mashed.
Mushy peas are a common dish in the UK and an all-time favorite. People eat them with their Sunday roasts at the local pubs or at grandma’s house. Although it has traditional origins, that doesn’t mean this recipe is old-fashioned. This recipe is an oldie with a twist!
What Goes Into This Recipe

- Peas: This recipe relies on frozen peas, making it easy any time of the year. When fresh peas are available, you can definitely use them instead.

How To Make Mashed Peas Vegan
Preparation Steps:
- Preheat the oven to 350 degrees F and line a baking sheet with parchment paper or a silicone mat.

Step 1: Start by cooking the peas. First, boil them in salted water for about 10 to 15 minutes, until they soften up.

Step 2: Meanwhile, combine the cauliflower, onion, and carrots on the lined baking tray. Then drizzle them with some olive oil, and season with salt and pepper to taste.

Step 3: Place the vegetables in the oven to bake for 20 to 25 minutes.

Step 4: When the peas are soft, drain and mash them with a fork and season with salt and pepper. Then cover with a lid and keep warm until the roasted vegetables are ready.

Step 5: Finally, serve up mashed peas with the roasted veggies on top and a sprinkle of sesame seeds and fresh thyme.
Toni’s Recipe Tips
- In spring or early summer, try making this recipe with fresh peas.
- Don’t overcook the peas. For an ultra-bright green color, cook them just until tender.
- Cut the roasted vegetables into similar-sized pieces so they cook evenly.
- Give the veggies room when cooking. Use a large enough baking pan so the veggies can be spread out. They will cook more quickly and crisp up better.

Variations and Substitutions
- Add some herbs: Mix in chopped basil, mint, parsley, tarragon and thyme to the mixed peas to change up the flavor.
- Make it spicy: Add a pinch of red pepper flakes or a dash of cayenne pepper.
- Add more protein: Add some nuts such as sliced almonds or chopped walnuts, some crispy chickpeas, or toasted pepitas to the top of your plate of mashed peas.
What to Serve with Mashed Peas
Here are some of my favorite ways to serve mashed peas.
- Comforting sides: Add on a batch of these peas along with Vegan Scalloped Potatoes, Vegan Mashed Potatoes, and Rosemary Roasted Potatoes creating hearty and satisfying meals.
- As a side to your favorite main dish. BBQ Cauliflower Wings, White Bean Burgers, Crispy Tofu Sticks, and Buttery Lemon Tofu.
