Save These stuffed portobello mushrooms deliver all the comforting flavors of traditional lasagna in a low-carb, gluten-free package. Large mushroom caps are filled with a creamy ricotta mixture blended with mozzarella, Parmesan, fresh basil, garlic, and oregano, then topped with marinara and extra cheese before baking until golden and bubbly.
The entire dish comes together in just 50 minutes, with only 20 minutes of active prep time. Each serving provides 17 grams of protein while keeping carbohydrates at just 13 grams, making it an excellent option for those watching their carb intake without sacrificing satisfaction.
One of the best features is their freezer-friendly nature. Simply cook, cool completely, wrap individually in foil, and freeze for up to 2 months. Reheat straight from the fridge in a 375°F oven for 15–20 minutes for a quick weeknight dinner.
Pair with a crisp green salad or garlic bread for a complete meal, or add spinach or sautéed vegetables to the ricotta filling for extra nutrition.
My friend Sarah came over for dinner last winter and declared these the best comfort food she had eaten in years. She couldnt believe something so satisfying could be so light on carbs. We ended up making three batches that night just to stock her freezer.
I discovered this trick during my low-carb experiment last year. Now even my pasta-loving husband requests these over traditional lasagna. The mushrooms get so tender and meaty you honestly dont miss the noodles at all.

Save These became my go-to for new parents and anyone recovering from surgery. Something about individual portions feels like such a thoughtful gift.
Make It Ahead
I love assembling these in the morning and keeping them in the fridge until dinner. The flavors have time to mingle and the filling firms up a bit for easier handling.
Freezing Like A Pro
Wrap each cooled mushroom tightly in foil before freezing. This extra step prevents freezer burn and makes reheating so much easier later.
Serving Ideas
A crisp green salad with balsamic vinaigrette cuts through all that richness perfectly. Sometimes I roast broccoli alongside the mushrooms for a complete sheet pan dinner.
- Garlic bread still works wonderfully alongside these low-carb lasagna cups
- Try adding spinach to the ricotta filling for extra nutrition
- A glass of red wine makes this feel like a proper Italian dinner
Save Hope these become a freezer staple in your house like they are in mine.
Recipe FAQs
- → Can I make these stuffed portobellos ahead of time?
-
Yes, you can prepare the stuffed mushrooms up to 24 hours in advance. Assemble everything, cover tightly, and refrigerate until ready to bake. You may need to add 2–3 minutes to the baking time if baking cold from the refrigerator.
- → How do I prevent the mushrooms from becoming soggy?
-
Remove the gills and stems completely, which helps prevent excess moisture. Brushing with olive oil and roasting gill-side up at 400°F helps the mushrooms maintain their structure while cooking.
- → Can I use other types of mushrooms?
-
Large portobello caps work best because of their size and sturdy texture. Button or cremini mushrooms would be too small for this filling, though you could use them to make bite-sized appetizers with reduced cooking time.
- → What can I use instead of ricotta cheese?
-
Cottage cheese blended until smooth makes a good substitute. For a vegan version, use plant-based ricotta alternatives and omit the egg, or blend tofu with nutritional yeast, garlic, and herbs.
- → How should I store leftovers?
-
Store cooled stuffed mushrooms in an airtight container in the refrigerator for up to 4 days. Reheat in a 350°F oven for 10–15 minutes, or microwave individual portions for 1–2 minutes until heated through.
- → Can I freeze these uncooked?
-
For best results, freeze them after cooking. Freezing uncooked stuffed mushrooms can affect texture and lead to excess moisture. Cook, cool completely, wrap tightly in foil, and freeze for up to 2 months.
