Preparation Tips

Clean and prep:
Remove stems and carefully scrape out gills with a spoon to create space for filling.
Initial roasting:
Pre-roasting mushrooms releases excess moisture, preventing a watery final dish.
Building flavor:
Sauté aromatics until golden before adding spinach for enhanced taste.
Temperature matters:
Allow spinach mixture to cool slightly before combining with cheese.
Proper filling:
Pack filling firmly but gently into caps for even distribution.
Careful baking:
Monitor closely during final bake to achieve golden brown topping without burning.

Storage Guide

Store leftovers in an airtight container for up to 3 days. Reheat in a 350°F oven until warmed through. The filling can be frozen separately for future use.

Frequently Asked Questions

→ Can I make these in advance?
Absolutely! Prepare and fill the mushrooms the day before, store them covered in the fridge, and just pop them in the oven when it's time to eat.
→ What goes well with these mushrooms?
They’re perfect with roasted veggies, a side salad, or even served as a side dish for grilled chicken or steak. You can also enjoy them as a standalone dish.
→ How do I clean portobello mushrooms properly?
Use a damp cloth or a mushroom brush to gently clean them. Avoid rinsing under water because they soak up moisture. Remove the stems and carefully scoop out the gills using a spoon.
→ Can frozen spinach work?
Of course! Just make sure it’s fully thawed and squeeze out all the liquid before using. You’ll need about half a cup of thawed spinach.
→ What can I swap for ricotta cheese?
Try using drained cottage cheese, cream cheese, or even Greek yogurt. Keep in mind that each will give the filling a slightly different consistency and flavor.

Yield: 4 Servings (4 stuffed mushrooms)

Dietary: Low-Carb, Vegetarian, Gluten-Free

Ingredients

→ To Prepare the Mushrooms

01 4 large portobello mushrooms with stems and gills removed
02 2 tablespoons olive oil, divided into two parts

→ For the Stuffing

03 1/2 cup chopped onion, diced as finely as you can
04 1 teaspoon garlic, minced well
05 2 cups chopped fresh spinach leaves
06 1/2 cup ricotta cheese
07 1/4 cup grated Parmesan cheese, with a little extra to sprinkle on top if you like
08 1/4 teaspoon ground black pepper
09 1/4 teaspoon salt
10 1/4 teaspoon nutmeg, optional if you like that flavor
11 1/2 cup shredded mozzarella cheese

Instructions

Step 01

Turn your oven on to 375°F (190°C). Cover your baking tray with a sheet of parchment paper. Coat both sides of the mushroom caps with olive oil and lay them out gill-side up on the baking tray.

Step 02

Let the mushroom caps bake for around 10 minutes until they start giving off their liquid. This will stop the finished dish from being overly watery.

Step 03

While the mushrooms are in the oven, warm the leftover olive oil in a big pan on medium heat. Toss in the garlic and onions, cooking until soft—this takes about 3-4 minutes. Then, stir in the spinach and cook for another 2-3 minutes until it’s wilted. Take the pan off the heat and let the mix cool for a few minutes.

Step 04

Mix the cooked spinach, garlic, and onion mixture with ricotta, Parmesan, salt, pepper, and nutmeg (if you’re using it) in a bowl. Stir everything together so it’s combined evenly.

Step 05

Scoop the cheese-spinach mix into the mushroom caps, dividing the filling evenly. Sprinkle shredded mozzarella cheese over the top of each filled mushroom.

Step 06

Put the stuffed mushrooms back in the oven for 15-20 minutes. You’ll know they’re done when the cheese gets all bubbly and starts browning.

Step 07

Sprinkle more Parmesan cheese if you want, and serve the mushrooms while they’re nice and warm!

Notes

  1. Scraping out the gills from the mushrooms makes more space for the stuffing and keeps the dish looking bright.
