Hearty portobello mushrooms filled with creamy ricotta and wilted spinach in 30 minutes.
Avo's Tip
Press excess moisture out of the spinach so the filling stays creamy, not watery.
If your mushrooms release liquid while baking, blot gently before stuffing.
For extra browning, switch to broil for the final 1–2 minutes.
No portobello caps? Large cremini mushrooms work for individual portions.
No ricotta? Cream cheese thinned with 1 tbsp milk gives a similar creamy filling.
No spinach? Kale or arugula work — wilt them first in a hot pan before mixing in.
COMMON QUESTIONS
Frequently Asked Questions
Everything you need to know before you start cooking.
Can I swap the ricotta?
Yes. Blended cottage cheese or cream cheese both work well. For tang, add a little goat cheese.
Can I make these ahead?
Prep the filling and mushrooms up to a day ahead. Assemble and bake just before serving for best texture.
Any easy variations?
Swap spinach for kale (cook it first), add chopped sun-dried tomatoes, or change up the cheese—fontina or gruyère are great options.
Storage & Reheating
Fridge: Store in an airtight container for up to 3 days.
Reheat: Warm in a 350°F oven for 10–12 minutes to keep the mushrooms tender. Microwave: Works in a pinch (1–2 minutes), but texture will soften. Freezer: No-the cheese filling changes texture after freexing.
Why It Works
Uses big, hearty portobello caps that stand in for a main ingredient—no tricky prep required.
The filling is a quick sauté and a simple mix-together, and everything finishes in one oven bake so cleanup is minimal.

Ingredients
1
4 large portobello mushroom caps
2
2 cups fresh spinach, chopped
3
1 clove garlic, minced
4
½ tsp kosher salt
5
¼ tsp black pepper
6
¼ tsp crushed red pepper flakes (optional)
7
1 tbsp olive oil
8
¾ cup shredded mozzarella cheese
9
¼ cup grated Parmesan cheese
10
3 oz cream cheese, softened
11
2 tbsp Breadcrumbs or Panko
12
2 tbsp Fresh Parsley , chopped
Instructions
1
Preheat the oven to 400°F (205°C) and line a baking sheet.
2
Brush mushroom caps with olive oil and season with salt and pepper.
3
Roast gill-side up for 8 minutes until just tender and lightly juicy.
4
Sauté spinach in a skillet over medium heat until fully wilted and dry, about 2 minutes.
5
Mix spinach, mozzarella, Parmesan, cream cheese, garlic, and red pepper flakes until smooth and creamy.
6
Fill each mushroom cap generously with the spinach-cheese mixture.
7
Bake for 12 minutes until the tops are bubbly and lightly golden.

Quick Fixes
Watery mushrooms: Pre-roast caps gill-side up for 8 minutes to drive out moisture before adding filling.
Filling too loose: Make sure spinach is squeezed dry and let the filling sit a few minutes to firm before stuffing.
