Keto Portobello Mushroom Mini Pizzas

Step 1Preheat oven to 190 °C/ 375 °F (conventional), or 170 °C/ 340 °F (fan assisted) and place the mushrooms on a baking sheet. Divide the pesto between the mushrooms. (You can reserve the portobello stems and add them on top of your breakfast omelet.)
Tip for the perfect portobellos: Baked mushrooms can be watery. To reduce the moisture, brush the portobellos with a small amount of ghee or olive oil and bake without the topping for 10-12 minutes. Add the topping and broil on high for another 2-3 minutes.

Step 2Fill the centers with the cheese then top with your desired toppings.

Step 3Bake for 10-15 minutes, just until the cheese is bubbly and the mushrooms are starting to soften.

Step 4Serve immediately, optionally sprinkled with red pepper flakes, or refrigerate for up to a day and reheat before serving.
