I love this mushroom sauté with caramelized onions!  Is that too bold to say?  Usually I would tell you a little story about how this recipe came to be and end with how delicious it is, but not today my friends.  I’m changing it up and going BIG!  I’m shouting it from my desktop that this sauté is the BOMB!

The key to making this amazing, is going to be by following the directions. I know, I hate following directions to!  I prefer to think of directions as “suggestions”, or at least when it comes to cooking.  Usually I throw a “little of this” and mix it with a “little of that” and BAM, you’ve got dinner!  But if you want all the flavors & textures to come out perfectly, then be sure to do these 2 extra steps……

Toast those pumpkin seeds! Don’t skip this. Raw seeds can be satisfying to eat on their own (meh, 😜kinda) but toasting them releases their natural oils and deepen flavors that wouldn’t be exposed otherwise.   Toasting them also increases their crunch which is what makes it the perfect compliment to our mushroom sauté.  SO if you don’t want to sacrifice flavor or texture, toast away!

Step 2 you don’t want to skip….caramelizing the onions.  Don’t worry, you still use 1 skillet for everything (🙌🏼”yay”), but this comes after the seeds are toasted and before the mushrooms start sautéeing.  Caramelized onions add the sweet & savory element to this mushroom sautée but the intense flavor that only happens when the onions cook down alone.  Trust me, caramelize them on their own, you won’t regret it.

This makes a delicious side dish all on its own, but you can also pair with your favorite grain to make it a meal, like we did. I’m even thinking how amazing this mushroom sauté would taste top of a veggie burger too.  You just HAVE to make them and share the creative way you incorporated them into your next meal!

You guys are going to quickly agree that this is the best mushroom sauté you have ever had!

Mushroom Sauté with Caramelized Onion




Yield 3-4 servings

This little plate is loaded with irresistible flavor.  Earthy, meaty mushrooms dance between layers of sweet caramelized onions & tender baby spinach with the delightful crunch of toasted pumpkin seeds. 


  • 1/3 cup raw pumpkin seeds
  • 1 small vidalia onion, sliced into thin rounds
  • 2 garlic cloves, minced
  • 1/2 pound baby bella mushrooms, remove stems & quarter
  • 2 teaspoons coconut oil
  • Pinch of sea salt
  • 1 teaspoon dried thyme
  • 2 cups baby spinach leaves, washed and dried
  • 1 tablespoon white balsamic vinegar 
  • Fresh ground pepper
  • Prepared grain such as rice, quinoa or pasta if desired. 


Preheat a dry skillet over medium.  When hot, toast the pumpkin seeds just until golden. Remove from pan & set aside to cool.

Prepare your veggies.

Place skillet back on stove & melt 1 teaspoon of coconut oil over medium heat. Add onion & sprinkle with a pinch of sea salt. Stir occasionally, letting the onions caramelize, approximately 10 minutes. Remove onions from pan and set aside.

Place skillet back on stove and melt remaining teaspoon of coconut oil.  Add mushrooms and let them cook down into a pretty brown color.  Sprinkle with thyme and add garlic then cook another minute for flavors to blend.  Fold in spinach leaves and balsamic vinegar.  When spinach starts to turn bright green, add caramelized onions then season with fresh ground pepper and a pinch of salt.

Serve in a bowl or on a plate & sprinkle with toasted pumpkin seeds. Enjoy as is, as a side dish or with your favorite grain (we like rice).

    I LOVE mushrooms and caramelized onions! This is totally my kind of meal, and I’m with you, I usually create a meal from adding a little (or a lot) of this and that until it’s just right.
