Peas are one of my favorite side dishes but they can be a little plain. The simple addition of sautéed onions and mushrooms turns something ordinary into something special that can be served for a regular family meal or a special occasion.

How To Serve Buttery Peas and Mushrooms

This pea side dish goes well with so many foods. I especially like it with steak, roast pork, or Chicken and Gravy. The earthiness of the mushrooms goes so well with the sweetness of the peas. The peas are simmered in chicken broth for extra flavor.

A bag of frozen peas is used for convenience. Peas are one of my favorite frozen vegetables to use.

Recipe Tips

  • You can use cremini mushrooms or white mushrooms and either a sweet onion or yellow onion.
  • When you saute the onions and mushrooms, use as big a skillet as you have. You want the mushrooms to be really spread out, not crowded so that they brown nicely. If they are too crowded, they will steam.
  • If you want this dish to be vegetarian, use vegetable broth instead of chicken broth.
  • To make it spicy, add 1/2 teaspoon of crushed red pepper flakes.


  • For a creamier dish, add a splash of heavy cream or a dollop of sour cream.
  • Swap out cremini mushrooms for shitake mushrooms for a more robust flavor.
  • Add a few teaspoons of finely chopped fresh herbs like parsley, rosemary, or thyme for more flavor.
  • Add grated Parmesan cheese just before serving.
  • Add a few slices of cooked and crumbled bacon.

Don’t be afraid to experiment with this recipe and make it your own.

Recommended Equipment

You can use any large pan to cook the peas and mushrooms. Non-stick is usually my go-to, but stainless steel or cast iron work well too.

    Here’s what I did to make this with what I had on hand: cooked the mushrooms first separately in batches so they were browned properly and looking good, set on a plate. I was out of yellow onion (weird right) – so I used the bulbs off of a bunch of spring onions chopped big. I also added dried thyme (suggested in another recipe) and browned chopped fresh garlic. Had chicken fond/bouillon but halved it with mushroom bouillion. Was SO SO good.
