A quick, simple side dish with tender sautéed mushrooms and onions, fresh garlic, and bright green peas added at the end so they stay vibrant and tender-crisp.

Easy Side Dish for Dinner
Peas always seem to end up as an afterthought at dinner, but this buttery peas with mushrooms recipe makes them feel like the best part of the meal. Sweet green peas are tossed with buttery mushrooms, onion, garlic, and a few simple seasonings for an easy side dish everyone loves.
This recipe comes together in one skillet in about 10 minutes, which makes it perfect for busy weeknights when you need something quick on the table. It pairs well with just about everything—meatloaf, roasted chicken, pork chops (i love them in the instant pot!), steak, and definietely mashed potatoes. I recently served it with my Salisbury Steak for dinner and everyone loved it. The buttery peas and mushrooms go so well with the rich gravy.
If you love cooking with peas I have lots more pea recipes to try.
Recipe Tips & Ingredient Notes
- Frozen peas work perfectly here and there’s no need to thaw them first. Just toss them right into the skillet and cook until warmed through. This keeps them bright green and tender without becoming mushy. Fresh peas can also be used, but they’ll need a little extra cooking time to soften.
- Don’t Overcook the Peas! The peas only need a few minutes in the skillet. You’re just warming them through. Overcooking can make them soft and dull in color, so keep an eye on them and remove from heat once they’re bright green and tender.
- I prefer fresh mushrooms for the best texture and flavor. They cook down beautifully with the onions and butter and add so much savory flavor to the peas. In a pinch, a drained can of mushrooms (or even two cans) works too.
