I can’t even begin to tell you how often I pull out a skillet, toss in sliced onions and mushrooms, a little bit of olive oil, salt and pepper to go along with whatever else I’ve prepared for our meal.

Really, it couldn’t be any easier.

Or better.

That’s the best thing about simple as can be recipes. You just turn to them to help finish out a meal and take it to a whole new level than if you’d not included it in the first place.

For example, I can’t remember the last time we’ve made hamburgers and not had mushroom and onion saute to go along with it.

I think that’s what they mean when they say a recipe is a staple in your family.

If I’m feeling really fancy, I’ll even toss in some fresh herbs to go along with it and amp up the flavors even more. Thyme, rosemary, or just a bit of parsley all taste delicious.

  1. 5 stars
    I tried it today for my housewarming party, and it was amazing! Definitely the best thing that I served and it was super easy to to. A++

  2. I love this recipe. I’m about to make it right now but I have too many mushrooms to eat in one day. Can I freeze them after I cook them?

    1. Sure – Just be sure to let it cool completely before freezing. Enjoy! Thanks Linda!

    Instead of yellow onions I used red onions, it has a more sweeter/more savory taste.  Plus thinly slicing your mushrooms into straws instead of chips helps them soak up more flavor.  Good recipe overall, though!
