You can find large portobello mushroom caps at most grocery stores in the produce section—look for caps that are 4-5 inches wide with firm, dry surfaces. Whole Foods and Trader Joe's typically have excellent quality mushrooms. For marinara sauce, I recommend Rao's Homemade or Victoria brands as they have no added sugar and fit perfectly into Optavia guidelines. Find turkey pepperoni at any major supermarket in the deli or refrigerated meat section.
Don't have turkey pepperoni? Use cooked ground turkey seasoned with Italian herbs, or lean chicken sausage crumbles for protein. If you can't find low-sugar marinara, make a quick sauce with crushed tomatoes, garlic, and Italian seasoning. Part-skim mozzarella keeps this recipe lean, but you can use full-fat in moderation. Scraping out the dark gills prevents excess moisture and creates more room for toppings.
Store fresh portobello mushrooms in a paper bag in the refrigerator for up to 5 days—avoid plastic bags which trap moisture. Keep marinara sauce refrigerated after opening and use within 7 days. These pizzas are best enjoyed fresh from the oven but can be reheated in a 350°F oven for 5 minutes.
Step-by-Step Instructions for Optavia Portobello Pizza
Let me walk you through this simple process that delivers satisfying pizza flavor without the carbs.
👨🍳 Step 1: Prep the Portobello Caps
Start by gently cleaning your portobello mushroom caps with a damp paper towel—don’t rinse them under water as they’ll absorb moisture and become soggy. Remove the stems by twisting them off at the base, then use a spoon to scrape out the dark gills from the underside. I always remove the gills because they release liquid during cooking and can make your pizza watery.
Pat the caps completely dry with paper towels, then brush both sides lightly with olive oil and season with salt and pepper. This pre-seasoning step ensures the mushrooms themselves are flavorful, not just bland vessels for toppings.
🔥 Step 2: Pre-Bake the Mushroom Crusts
Place the mushroom caps gill-side up on a parchment-lined baking sheet and bake at 400°F for 8-10 minutes. This pre-baking step is crucial—it releases excess moisture from the mushrooms so your finished pizzas won’t be soggy. You’ll see liquid pooling in the caps; carefully pour this off or blot with paper towels before adding toppings.
🥘 Step 3: Add Toppings and Finish Baking
Spread 2 tablespoons marinara sauce inside each pre-baked cap, staying within the edges. Sprinkle with reduced-fat mozzarella cheese and add your lean protein and veggie toppings. I like to use turkey pepperoni and diced bell peppers for maximum flavor with minimal calories.
Return to the oven and bake for 5-7 minutes until the cheese melts and turns golden brown around the edges. Let them cool for 2-3 minutes before serving—this allows the cheese to set slightly so toppings don’t slide off. Garnish with fresh basil and enjoy immediately while the cheese is still gooey!
Storing and Reheating This Recipe
Short-Term Refrigerator Storage: Store your leftover portobello pizzas in airtight containers lined with paper towels to absorb excess moisture—the mushrooms will continue releasing liquid as they cool. I place a paper towel both under and over the pizzas, then seal the container tightly. Refrigerate at 40°F or below for up to 3-4 days maximum. The cheese and toppings hold up well, but the mushroom caps will soften considerably after day three. For best results, store each pizza separately rather than stacking them, which can make the toppings slide off and create a soggy mess. ❄️
Freezer Storage Strategy: While I don’t typically recommend freezing these pizzas due to the mushrooms’ high water content, you can freeze them for up to 2 months if needed. Wrap each pizza individually in plastic wrap, then again in aluminum foil to prevent freezer burn. The texture won’t be quite as good as fresh—the mushrooms become softer and release more moisture when thawed—but the flavor remains intact. Thaw overnight in the refrigerator on a paper towel-lined plate to catch excess liquid. Never thaw at room temperature, which can create food safety issues.
Oven Reheating Method: This is my preferred approach for maintaining the best texture. Preheat your oven to 375°F and place the pizzas on a parchment-lined baking sheet. Blot any excess moisture with paper towels first, then reheat for 8-10 minutes until the cheese is bubbly and the edges crisp up slightly. If the cheese looks dry, add a small sprinkle of fresh mozzarella before reheating. The oven method helps evaporate some of the moisture the mushrooms released during storage, giving you a texture closer to freshly made. 🔥
Microwave Reheating: For quick lunches, microwave on a microwave-safe plate lined with a paper towel at 70% power for 90 seconds to 2 minutes. Place another paper towel on top to absorb steam and prevent the cheese from becoming rubbery. The lower power setting prevents the mushrooms from becoming waterlogged while heating evenly. I’ll be honest—microwaving makes the mushroom softer and releases more moisture, so it’s not ideal but works when you’re short on time. Let it rest for 30 seconds before eating to allow the temperature to equalize.
Quality Preservation Tips: The key to successful reheating is managing moisture. Before storing, let the pizzas cool completely at room temperature for no more than 2 hours, then refrigerate immediately. When reheating, always use paper towels to absorb excess liquid that accumulates during storage. if your reheated pizza seems watery, place it under the broiler on high for 1-2 minutes to evaporate moisture and crisp the cheese—watch carefully to prevent burning. Fresh toppings like basil or arugula should be added after reheating rather than before storage for the best flavor and texture.
