I have always had an affinity for spinach and artichoke dip. I'm all in if it's on the menu at a popular chain restaurant. If it's served at a party, you'll find me by the snack table!
So, to cure my cravings, I like incorporating these flavors into other dishes like this spinach artichoke risotto, this spinach artichoke frittata, and now these spinach artichoke-stuffed portobello mushrooms.
The mushrooms are meaty and satisfying, and the filling is creamy and cheesy. Together, they are delicious as both a main dish and a side dish.
Ingredients
- Portobello mushroom caps are large and perfect for filling. Their meaty texture makes them satisfying for both meat-eaters and vegetarians.
- Artichoke hearts - Use canned or frozen artichoke hearts. If using frozen, thaw and drain before adding to the recipe. Skip the jarred marinated artichokes - instead, save these for a meat and cheese platter.
- Swiss cheese - Use freshly shredded cheese for the best taste and melting quality. Fontina, Gruyere, and Monterey Jack are also great options.
- Creamed spinach - I love using frozen creamed spinach. It's a great staple ingredient to keep on hand and adds just the right amount of creaminess, like in these spaghetti squash boats. Green Giant is my go-to for cream spinach.
Step-by-step instructions
Please see the recipe card for complete instructions and ingredient amounts.
Preparing portobello mushrooms
- Use a damp paper towel to brush off dirt from the mushrooms' surface. TIP: Mushrooms should never be washed because they will absorb too much water and become soggy.
- To clean the underside of the mushrooms, twist off the stem and, using a spoon, scrape out the gills. (Image 1)
- Place them stem-side down on a parchment-lined baking sheet. Brush the outside of the mushroom caps with oil. (Image 2)
- Bake for 10-15 minutes until softened, but not collapsed. We want the mushroom caps to retain their shape to hold the filling.
- Drain any liquid that was released during the cooking process and blot dry.
- Place the mushrooms stem-side up on a clean baking sheet or baking dish. Set aside.
Preparing the filling
- In a small bowl, combine the breadcrumbs and Parmesan cheese.
- In a large skillet over medium-low heat, melt the butter. Pour half of the butter into the breadcrumb mixture. Toss to combine. Set aside.
- To the remaining butter in the skillet, add the shallots and artichoke hearts. Cook for 3-4 minutes until softened. (Image 3)
- Add the creamed spinach and cook for 1-2 minutes until warmed through. Add the cheese. (Image 4)
- Stir until the cheese is melted. Add the lemon juice, cayenne, and salt and pepper to taste. (Image 5)
- Spoon the mixture into the mushroom caps. Top with the breadcrumb mixture. (Image 6)
- Bake until bubbly and golden brown.
Recipe FAQs
While the gills are technically edible, most prefer to remove them because they can have a bitter taste. The dark color of the gills often turns the rest of the dish a muddy brown color, which isn't very appetizing.
Always clean mushrooms with a damp cloth. If washed with water, they act like sponges and will become waterlogged.
Secondly, pre-bake mushrooms to release some of their moisture before adding the stuffing.
As a main dish for lighter appetites, serve with a house salad and ciabatta garlic bread for dinner or pair with fruit salad with anise syrup for brunch.
As a side dish for heartier appetites serve with flat-cut corned beef or pork tenderloin with caramelized onions and apples.
