Ingredient Notes For This Stuffed Portobello Mushroom Recipe
- Portobello Mushrooms: Look for large unbroken portobellos caps (sometimes called portabella.) If they have the stems attached, simply break the stems off by snapping them off at the base. Use a spoon to scoop the black gills out of the center of each cap if you like.
- Ground Beef: Look for lean Grass-fed organic beef, preferably from a local source. Alternatively, you can substitute Impossible Burger meat or ground turkey instead if you do not eat beef.
- Breadcrumbs: To help bind the filling, you will need some dry unseasoned breadcrumbs. (If you happen to have Italian Seasoned breadcrumbs, they work fine too.) If you are on a grain-free diet you can substitute almond flour. Alternatively, for gluten-free diets, use Ian’s gluten-free panko instead.
- Marinara: To give the lean beef saucy moisture, I added in some Marinara on top. Check out the nutrition labels and look for those with lower fat and calories. I like Primal Kitchen Tomato Basil Marinara Sauce if you can find it. It is only 50 cals per serving, almost half that of some other premium brands!
- Cheese: For convenience I chose to top these off with pre-shredded cheese. I like Italian Cheese Blend for this recipe to compliment the Italian inspired flavors.
Step By Step Instructions To Make This Recipe
Step 1: Place large skillet in oven on center rack. Preheat oven to 400 degrees F. Meanwhile, gently knead beef, egg, breadcrumbs, Italian seasoning, ¾ teaspoon salt and pepper in a medium bowl.
Step 2: Brush oil all over tops and bottoms of the portobello caps. Sprinkle with the remaining ½ teaspoon kosher salt.
Step 3: After the beef mixture is combined, divide it into four even amounts, patting them into patties. Fill portobello caps with the beef mixture. Next, remove the hot skillet from the oven. Place portobellos, meat side up into the skillet and return the skillet to the oven.
Step 4: Next, bake the stuffed mushroom caps until the beef is browned on top and the mushroom is softened and wilted. Spoon marinara sauce over the beef and top with cheese. Finally, return the skillet to the oven. Continue baking them until the meat is cooked through, the marinara is hot and bubbling and the cheese is melted, 4 to 6 minutes longer. Let cool slightly before transferring to plates with a slotted spatula.
Expert Tips and FAQs
The gills are edible, however they can turn recipes black or grey because they are highly pigmented. I prefer to remove them, and recommended scraping them out with a spoon.
Either spelling is considered correct, and was actually created as part of a marketing campaign in the ’80s to make these seem more “gourmet!”
They can be stuffed with so many different fillings, the possibilities are endless. Try using turkey seasoned with herbs and topped with onions and cheese like these from EatingWell. Or make a vegetarian filling like for these Stuffed Bell Peppers.
Yes these beef stuffed portobellos can be made as an appetizer! You can use crimini mushrooms (which are actually immature portobellos) to make this an appetizer recipe. Carefully remove the stems with a pairing knife and then scrape out any gills to make space for the filling. Make sure that the mushrooms don’t topple over in the skillet by slicing a small sliver off the rounded edge of the cap so they stand up and don’t roll. Bake them until an instant read thermometer registers 165 degrees F in the center of the filling. Also check out our Healthy Stuffed Mushrooms appetizer recipe as well.

Notes
Ingredient Notes:
Ground Beef: To make this vegetarian, substitute Ground Impossible Burger for the beef. This can also be made with ground turkey. Use moistened hands to handle the filling, as turkey is more “sticky” than beef.
Breadcrumbs: To help bind the filling, you will need some dry unseasoned breadcrumbs. (If you happen to have Italian Seasoned breadcrumbs, they work fine too.) If you are on a grain-free diet you can substitute almond flour. For gluten-free diets, use Ian’s gluten-free panko instead.

Fantastic taste and so easy to make. One stuffed mushroom cap was a hearty meal! It was too much for me. I may put 1/8 lb beef in each instead of a 1/4 as the recipe suggests, and get 8 mushroom caps instead of 4, so I have a smaller meal for me, and the big eaters at home can have two.

Found your recipe today and I’m using yours to vamp up midsized baby bellas and what I have at home to use. I’m adding finely chopped Vidalia onion, fresh basil, and black olives to the mix… Thanks for the recipe!
That sounds absolutely delicious, Susie. Thank you for the great comment!
I wasn’t sure this would turn out good. My husband claims to hate mushrooms, however, we both loved this recipe!! Loads of taste, everything seems to blend perfectly, could not have asked for a better meal. Thank you for this recipe!
★★★★★
What a wonderful compliment! Thank you so much.
So good! My husband said he was feeling doubtful but that I should add this recipe to my go-to recipe list.
Two changes, that didn’t change flavor. Since I do low carb / keto / diabetic eating, I subbed grated zucchini for the bread crumbs. I also found that the mushrooms released a ton of juice, and it dripped on me, so I ended up putting them stuffed mushrooms on a small cookie-cooling rack on top of the baking sheet. (And saved the mushroom juice to umami up a stew or chili)
This super easy and delicious meal has become such a staple in this household! I love making them just as much as I love eating them!
★★★★★
Thanks so much Abigail! I’m so glad you love it! Food that’s fun to make is always that much better!

★★★★★
I am glad you like them Lauren. I appreciate the rating and review.
Delicious! I followed it exactly and I was very pleased with the end result. Since I’m feeding littles, I served it over a little pasta. Otherwise I would’ve served it with roasted potatoes.
★★★★★
My kids love pasta too. Glad your family likes them as well!
I just made the “Italian beef and marinara stuffed portobellos” tonight and they were a hit! There were easy to prepare although others may think a lot of effort went into the end result! I think the recipe was perfect as-is and I didn’t alter anything.
So glad you like them!
I love the idea of studding a portobello mushrooms with a beef filling like this. I have to try the recipe out!
Let me know how it goes!

Thanks Christine!
