Healthy portobello mushroom pizza. Keto friendly and gluten-free

Portobello mushroom pizza is a fun and healthy alternative to the calorie and carb loaded options we’re used to. And in this household, we’re gluten-free due to allergies. So it’s a complete win-win in our book. 

If you’re like us and pizza is one of your favorite foods, but you’re looking for a healthy pizza alternative, look no further! 

We first experimented with portobello pizzas when we were looking to reduce both carbs and calories. We also needed something quick and easy, without resorting to pre packaged meals or skimping on flavor. Pizza is our favorite quick and effortless meal. 

Since we’re strictly gluten-free in this household, we would normally buy premade cauliflower pizzas at Costco to keep on hand. But the amount of calories and garbage (not to mention lack of variety for toppings) still makes it a not-so-healthy option. While some people may think that gluten-free store bought products might be healthier, they can be just as high in carbs and are (a lot of the time) higher in calories. Add in the cost…and OUCH!

So we needed to switch things up a bit.

Without further ado, the recipe is below. Keep scrolling for step-by-step instructions with pictures, as well as additional topping ideas. 

healthy portobello mushroom pizzas. Quick and easy healthy recipe

Step 1:

Preheat the oven to 450 degrees fahrenheit. Spray a rimmed cookie sheet or baking pan with oil. Place the portobello mushrooms (stem side up) in the dish and remove the stems. Slice a small X into the bottom on the cap to help with draining.

Chop the stems up and set aside to include in the pizza toppings.

Step 2:

Cook up the ground turkey. While it’s cooking, evenly spread the pizza sauce on top of the portobello caps. 

When the ground turkey is close to being fully cooked, add the garlic and Italian seasoning. 

We like to crisp up the ground turkey with the seasonings to give it a flavor similar to pork sausage, but with less of the fat and calories!


Step 3:

Add the cooked ground turkey, sliced olives, chopped portobello stems and other toppings, leaving the cheese for last. 

If you have extra toppings that won’t fit on top, add them after the cheese has melted.

Step 4:

Place the pizzas in the preheated oven and bake for 8-10 minutes, until cheese is melted and the portobellos have softened.

Step 5:

Serve immediately and enjoy!

Take into consideration that the portobellos can only hold so many toppings. Have fun with it!
