They offer a healthier alternative to traditional pizza, providing the same satisfying flavors with fewer carbs. This recipe is perfect for family dinners, gatherings, or even as a hearty appetizer.

Frequently Asked Questions

Can I grill these instead of baking?
Yes! These stuffed mushrooms can be grilled over medium heat for about 15–20 minutes with the lid closed. Just be sure to use a grill-safe tray or foil to prevent them from tipping or leaking.

What can I substitute for sun-dried tomatoes?
You can swap sun-dried tomatoes with cherry tomatoes (halved), roasted red peppers, or even chopped olives for a different flavor profile that still adds a burst of tangy richness.

Can I use other types of mushrooms?
Portobello mushrooms are ideal for stuffing due to their size and meaty texture, but you could use large cremini or even big white mushrooms for mini versions. Just adjust the cook time accordingly, as smaller mushrooms will bake faster.
