Veggie Stromboli with Mushroom, Spinach and Mozzarella in Steps
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This ensures that your Stromboli will bake evenly and develop that golden-brown crust we all love.
Step 2: Sauté the Vegetables
In a large skillet, heat the extra virgin olive oil over medium heat. Add the chopped red onion and sauté for about 2-3 minutes, or until softened. Next, add the thinly sliced cremini mushrooms and continue to cook for an additional 5 minutes, stirring occasionally. Add the crushed garlic and spinach, cooking just until the spinach has wilted. Season the mixture with kosher salt, and then remove it from the heat to cool slightly.
Step 3: Roll Out the Dough
On a lightly floured surface, roll out your pizza dough into a large rectangle, about 12×16 inches. Make sure the dough is evenly rolled to ensure even cooking.
Step 4: Assemble the Stromboli
Spread the sautéed vegetable mixture evenly over the rolled-out dough, leaving about an inch of space around the edges. Sprinkle the shredded mozzarella cheese on top of the vegetables, distributing it evenly.
Step 5: Roll It Up
Starting from one long edge, carefully roll the dough over the filling, tucking in the sides as you go to enclose the filling completely. Pinch the seams to seal the Stromboli well to prevent any filling from leaking out during baking.
Step 6: Prepare for Baking
Transfer the rolled Stromboli to a baking sheet lined with parchment paper. Brush the top with the beaten egg white to give it a beautiful shine and golden color as it bakes. If desired, sprinkle sesame seeds on top for added texture and flavor.
Step 7: Bake
Place the baking sheet in the preheated oven and bake for 25-30 minutes, or until the Stromboli is golden brown and the dough is cooked through. Keep an eye on it to ensure it doesn’t over-brown.
Step 8: Serve
Once baked, remove the Stromboli from the oven and let it cool for a few minutes before slicing. Serve warm with marinara sauce for dipping, and enjoy every cheesy, veggie-packed bite!
Better-for-You Options
If you’re looking to make this Veggie Stromboli even more wholesome, consider these options:
- Use whole wheat pizza dough for added fiber and nutrients.
- Add more vegetables like bell peppers, zucchini, or artichokes for extra flavor and nutrition.
- Replace part of the mozzarella with a lower-fat cheese or a dairy-free alternative for a lighter version.
- Include fresh herbs like basil or oregano for added flavor without extra calories.
Troubles You Can Avoid
To ensure your Veggie Stromboli comes out perfectly every time, keep these tips in mind:
- Don’t overfill the Stromboli—ensure there’s enough space for the dough to seal properly.
- Allow the sautéed vegetables to cool slightly before adding them to the dough to prevent sogginess.
- Check doneness by tapping the bottom of the Stromboli; it should sound hollow when fully baked.
- Let it cool for a few minutes before slicing to maintain the integrity of the filling.
Keep-It-Fresh Plan
If you’re lucky enough to have leftovers, here’s how to keep your Veggie Stromboli fresh:
- Store leftover Stromboli in an airtight container in the refrigerator for up to 3 days.
- To reheat, place slices in the oven at 350°F (175°C) for about 10 minutes until warmed through.
- For longer storage, wrap the Stromboli tightly in plastic wrap and foil, then freeze for up to 2 months. Thaw in the refrigerator before reheating.
