Ingredients

• 1 lb ground beef (choose lean or your preferred fat content)
• 1 small onion, finely chopped
• 2 cloves garlic, minced
• 1/2 cup red bell pepper, finely diced
• 1/2 cup canned diced tomatoes, drained
• 1/2 cup shredded mozzarella cheese (or a -certified cheese alternative)
• 1/4 cup grated Parmesan cheese (optional, use a -certified version)
• 2 tablespoons olive oil
• 1 teaspoon dried oregano
• 1 teaspoon ground cumin
• 1/2 teaspoon smoked paprika
• Salt and freshly ground black pepper, to taste
• Fresh parsley or basil, chopped, for garnish

How To Make Beef Stuffed Portobello Mushrooms

Step 1: Prepare the Mushrooms

Begin by preheating your oven to 375°F (190°C). Carefully clean the portobello mushroom caps with a damp cloth to remove any dirt. Remove the stems and gently scrape out the gills with a spoon to make room for the filling. Lightly brush both sides of the mushroom caps with olive oil and place them on a baking sheet lined with parchment paper, gill side up. This will help them roast nicely without drying out.

Step 2: Cook the Beef Mixture

Heat 1 tablespoon of olive oil in a large skillet over medium heat. Add the finely chopped onion and sauté until translucent, about 3-4 minutes. Add the minced garlic and cook for another minute until fragrant. Next, add the ground beef to the skillet, breaking it apart with a wooden spoon. Cook until browned and cooked through, about 6-7 minutes. Drain any excess fat if necessary.

Step 3: Add Vegetables and Spices

To the cooked beef, stir in the diced red bell peppers and canned diced tomatoes. Sprinkle in the dried oregano, ground cumin, smoked paprika, salt, and pepper. Mix well and let the mixture cook for another 3-4 minutes, allowing the flavors to meld together. Taste and adjust seasoning as needed.

Step 4: Stuff the Mushrooms

Spoon the beef mixture evenly into each of the prepared mushroom caps, pressing gently to fill them well. Sprinkle the shredded mozzarella cheese generously on top of each stuffed mushroom, followed by a light dusting of grated Parmesan if using.

Step 5: Bake

Place the baking sheet in the preheated oven and bake for 20-25 minutes, or until the mushrooms are tender and the cheese is melted and golden brown. If you want a bubbly top, you can broil for an additional 2 minutes—just keep a close eye to prevent burning.

Step 6: Garnish and Serve

Remove the stuffed mushrooms from the oven and let them sit for a couple of minutes. Garnish with freshly chopped parsley or basil before serving. These are fantastic served alongside a fresh green salad or some roasted vegetables for a complete meal.

Expert Tips

• Make sure to clean the mushrooms gently to avoid waterlogging them, which can make the dish soggy.
• Remove the mushroom gills carefully as they can release moisture and turn the dish watery.
• If you want to reduce the fat content, choose lean ground beef or substitute with ground turkey or chicken.
• Use a good quality cheese that melts well—mozzarella is perfect for this recipe.
• Don’t skip draining the canned tomatoes well to prevent excess moisture in the filling.
• Customize the seasoning to your liking; fresh herbs like thyme or rosemary can add a lovely depth.
• For an extra layer of flavor, consider adding a splash of Worcestershire sauce or soy sauce (ensure it’s a gluten-free and -friendly brand) to the beef mixture.
• Allow the mushrooms to rest a few minutes before serving to keep the filling intact and flavors well combined.

Variations and Customizations

• Cheese Alternatives: Swap mozzarella for feta, goat cheese, or a dairy-free cheese if you prefer a different flavor or need a dairy-free option.
• Vegetarian Version: Replace beef with cooked lentils, chickpeas, or a plant-based ground meat substitute.
• Spicy Kick: Add chopped jalapeños or a dash of chili flakes to the beef mixture for some heat.
• Herbs and Spices: Experiment with fresh herbs like cilantro or mint, or add curry powder for a different twist.
• Additional Veggies: Incorporate finely chopped spinach, zucchini, or mushrooms stems for extra nutrition and texture.
• Sauce Topping: Drizzle a little tahini or a squeeze of lemon juice on top before serving for added brightness.

How to Store Leftovers

If you have any leftover beef stuffed portobello mushrooms, let them cool completely before storing. Place them in an airtight container and refrigerate for up to 3 days. To reheat, warm them in the oven at 350°F (175°C) for about 10-15 minutes or until heated through. Avoid microwaving if possible to prevent sogginess, but if you do use a microwave, heat in short bursts and cover loosely with a microwave-safe lid.

For longer storage, you can freeze the stuffed mushrooms. Wrap each one tightly in plastic wrap and then place them in a freezer-safe bag or container. Freeze for up to 2 months. To reheat, thaw overnight in the refrigerator and then bake in the oven as directed until heated through.

FAQ

Can I use other types of mushrooms for this recipe?

Yes! While portobello mushrooms are ideal because of their large size and meaty texture, you can use large cremini mushrooms or even baby bellas. Just adjust the cooking time slightly since smaller mushrooms will cook faster.

Is it necessary to remove the mushroom gills?

While it’s not absolutely necessary, removing the gills helps reduce moisture and prevents the mushrooms from becoming soggy. It also creates more space for the filling, resulting in a better overall texture.

Can I prepare the stuffed mushrooms ahead of time?

Absolutely! You can prepare the beef mixture and stuff the mushrooms a few hours in advance. Keep them covered in the refrigerator and bake just before serving. This makes it a great option for meal prep or entertaining.

What can I serve with beef stuffed portobello mushrooms?

These mushrooms pair wonderfully with a fresh green salad, roasted vegetables, quinoa, or a simple side of steamed rice. You can also serve them with a tangy yogurt sauce or a drizzle of balsamic glaze for added flavor.
