  • 1 tsp Dried Oregano
  • 1/2 tsp Dried Basil
  • 1/4 tsp Red Pepper Flakes or to taste
  • 1 tbsp Balsamic Vinegar
  • 1/2 tsp Salt or to taste
  • 1/4 tsp Black Pepper freshly ground, or to taste
For Garnish (Optional)
  • 2 tbsp Fresh Parsley chopped
  • 1/4 cup Parmesan Cheese grated, for serving

  • Wooden Spoon or Spatula

Method
 

Prepare the Mushrooms
  1. Clean the cremini mushrooms by gently wiping them with a damp cloth or a mushroom brush. Trim off the very ends of the stems. Slice the mushrooms about 1/4-inch thick and set aside.
Sauté Aromatics
  1. Heat the olive oil in a large skillet (at least 12-inch) over medium heat. Add the finely chopped yellow onion and sauté for 3-5 minutes until softened and translucent.
  2. Add the minced garlic to the skillet and cook for another 1 minute until fragrant, being careful not to burn it.
Build the Sauce
  1. Stir in the tomato paste and cook for 2 minutes, stirring occasionally, until it darkens slightly and becomes fragrant. This helps to deepen its flavor.
  2. Pour in the crushed tomatoes, dried oregano, dried basil, red pepper flakes, balsamic vinegar, salt, and black pepper. Stir well to combine. Bring the sauce to a gentle simmer.
Cook the Mushrooms
  1. Add all the sliced mushrooms to the skillet. It may seem like a lot, but they will cook down significantly. Stir to coat the mushrooms evenly with the sauce.
  2. Reduce the heat to medium-low, cover the skillet, and let the mushrooms cook for 10-12 minutes, stirring occasionally, until they release their liquid and soften.
  3. Uncover the skillet and increase the heat slightly to medium. Continue to cook for another 5-8 minutes, stirring frequently, allowing the liquid to reduce and the sauce to thicken to your desired consistency. The mushrooms should be tender and thoroughly coated.
Finish and Serve
  1. Remove the skillet from the heat. Taste and adjust seasoning if necessary.
  2. Stir in the fresh chopped parsley (if using). Serve hot, garnished with extra grated Parmesan cheese.

Notes

These savory pizza mushrooms are incredibly versatile. Serve them on toasted crusty bread for a quick appetizer, as a side dish alongside grilled meats, stirred into pasta, or as a flavorful topping for homemade pizza or scrambled eggs. For a richer flavor, add a splash of red wine along with the crushed tomatoes. To store, place cooled mushrooms in an airtight container in the refrigerator for up to 3-4 days.
