Why you need a frozen peas recipe

Occasionally, I find fresh peas at our farmer’s market.  And I pay for them.  They were not cheap.  But there is something rhythmic about shelling peas.  

I anticipate that these peas will taste much better than ones from the grocery store because they are so fresh!  I imagine all sorts of incarnations for them. I put effort into spotlighting them in my dishes.  

And I’m always disappointed.

Why?  Well, first,  the peas are typically not uniform in size.  In one pod, I’ll find miniature pea-lings peas next to others that are full-grown.  Weird.  I mean, they’re in the same pod.  

Also, the yield is paltry.  I’ve paid $5 for a lunch bag full of pea pods which only yields about 1 cup of shelled peas.  And lastly, they tend to be tough.  Not all, but some… and the point of having a straight-from-the-market “pea experience” is to have the freshest, most flavorful, pop-in-your-mouth reward.

After buying the farmer’s market peas for two years, trying everything to prepare them and being constantly disappointed, I waved the white flag.  I surrender.  And I’m happier about it.  Certain convenience foods make sense.  Frozen peas are one of them.  

They’ve been picked, blanched and packaged at their peak.  The manufacturers must put them through a sorting facility because I’ve never seen a pea-ling in any carton or bag I’ve ever bought.  And let’s not forget – they are available year-round and cost about $2.50/lb.  Sold.

And this frozen peas side dish is one I make again and again. It goes with everything, can be assembled in 15 minutes and mushrooms and peas are a classic combination.

  • Homemade Vegetable Broth – you don’t need much.
  • Olive Oil
  • Fresh Tarragon – fresh herbs make the difference in this dish.

How to make peas and mushrooms

  1. Heat olive oil in a skillet over medium-low heat and sweat the shallots in the pan until they’re tender and slightly translucent. Don’t let them brown. Transfer shallots to a small bowl.
  2. Add the remaining oil and increase heat to medium-high. Add the sliced mushrooms and saute until browned. Transfer mushrooms to a separate small bowl.
  3. Add the frozen peas to the pan with broth and heat over medium-high until the peas heat through.
  4. Remove from the heat and stir in the shallots, peas, tarragon, thyme, butter and lemon zest.
  5. Stir to combine, taste, and season with salt and pepper as needed.
combining the veg


  • Sweat garlic or onions instead of shallots.
  • Add parmesan cheese just before serving.
  • If you like spice, add a pinch of crushed red pepper flakes when sauteing the mushrooms.
  • Toss the peas side dish over cooked pasta for a vegetarian main course.
  • Add 1/4 cup of heavy cream and cook down for 2-3 minutes. It will cloak the peas with a lush sauce.

    I could tell you stories about the “fresh” produce from farmers markets. And I absolutely agree with you that it’s very hard to get the freshest of the fresh peas. Frozen is definitely a great choice! This recipe sounds delicious 🙂
