Unfortunately, the mushrooms burned after having them in the oven for 10 minutes at 450 so I had to throw away. They were completely flat and smoking. I would suggest turning the oven down to 350 and checking on them frequently to see if that helps. I'm not sure why mine turned out this way and others not.

Here we take the elements of a vegetarian lasagna filling—ricotta, spinach and Parmesan cheese—and nestle them into roasted portobello mushroom caps. The recipe works best with very large portobello caps; if you can only find smaller ones, buy one or two extra and divide the filling among all the caps. Serve with a tossed salad and a whole-wheat dinner roll or spaghetti tossed with marinara sauce.

So I followed the directions (heat up the caps first) and within five minutes my mushroom caps went completely flat....any ideas on what went wrong?
If you remove the gills (teaspoon does trick or grapefruit spoon) you may not notice an after-taste or "sour" taste as one mentioned. I also use steamed broccoli and roasted red peppers for a twist. Great jumping off point. Thanks.
I came home from the farmers' market with a couple of nice, big portobello mushrooms but no idea what to make. Expensive? Well, under $4 for two large mushrooms didn't break the bank and was waaaay cheaper than steak. In internet search yielded this recipe and I decided to give it a try. I'd also brought home a bag of tomatoes to roast, so I soon had homemade marinara too. Hubby didn't even miss having meat for dinner. Another commenter suggested adding sausage to the stuffing, and that WOULD be good too, but it would up the calorie count significantly, and I didn't feel anything was lacking from this dish "as is." We'll definitely make it again.
Great recipie, but really unrealistic if you live on a budget.
