Stuffed portobello mushrooms with spinach and artichoke are so easy to make! Serve these low carb stuffed mushrooms as an appetizer or side dish.
I’m a huge fan of spinach artichoke dip. I’m also a mushroom lover. The combination of the two makes one of the best vegetarian low carb recipes!
There aren’t that many carbs in portabella mushrooms. But there are carbs in artichokes and spinach. That’s why I don’t recommend eating a whole stuffed mushroom.
One medium artichoke has about 13 grams of carbohydrates, but over half the carbs are fiber. So if you count net carbs, it shouldn’t be an issue.
A single portobello mushroom cap has 4 grams of total carbs, most of which (3 grams) is fiber. And a cup of cooked spinach has about 7 grams of carbs with over half (4 grams) coming from fiber.
Because this is a vegetarian stuffed portobello mushroom recipe, the carbs are higher than ones with mainly meat. But if you count net carbs instead of total, each one of the stuffed mushrooms has under 10 grams of net carbs.
How to Make Artichoke and Spinach Stuffed Mushrooms
I’ve never made keto stuffed mushrooms before so I wasn’t really sure how much of the inside of the mushrooms to remove. I ended up cutting out the stems and scraping out the gills.
After the mushroom caps are prepared and placed on a baking sheet, olive oil is brushed on. Then, they are broiled on high for about 5 minutes on each side. This pre-cooks the mushrooms so they are more tender.
Although frozen chopped spinach was used for convenience in these stuffed portobello mushrooms, fresh spinach is always an option. It just needs to be steamed and then drained and chopped.
To make sure the spinach wasn’t too watery after cooking, it’s best to put it in a clean kitchen towel and squeeze out as much moisture as possible. Next, it’s mixed together with artichoke, cream cheese, sour cream, Parmesan cheese, and seasonings.
The filling should be piled on in a nice mound to top off each Portobello mushroom. Once the filling is evenly divided, freshly grated mozzarella cheese is sprinkled on top.
Finally, the stuffed portabella mushroom caps are baked at 375°F for about 10 to 15 minutes. To get the cheese topping to brown up nicely, the broiler may need to be turned on at the end of baking.
I kept the stuffed mushrooms on the center oven rack when baking. But for the last couple minutes, I turned the broiler on high just until the tops began to brown.
How to Serve Baked Stuffed Portobello Mushrooms
These gems are quite tasty alone, but I suggest eating only half as the carb count is rather high for a whole one.
A nice reverse seared steak would go wonderful with these yummy low carb spinach artichoke stuffed mushrooms!
There is quite a bit of filling in each mushroom cap so you’ll get a nice serving of veggies in these tasty bites. We all know that spinach is super healthy, but artichokes are great too.
If you don’t mind the extra work, regular button mushrooms could be stuffed as well for smaller bite sized appetizers. But I like the larger size of the stuffed portobello mushrooms and I think they have a better taste than the smaller button ones.
To cut back on carbs, the artichokes can be left out. Or they can be replaced with some browned ground meat like sausage or beef. The mushroom stems can finely chopped and added in as well.
And if you are one of those that likes bread crumbs sprinkled on top, just use seasoned crushed pork rinds instead.
