Whenever I'm in need of an easy and comforting vegetarian meal that serves a crowd and can be made in advance, I turn to lasagna. Although the classic variation is loaded with meat, there are tons of vegetable lasagnas out there, from asparagus to spinach-pesto. My latest favorite is mushroom lasagna. Not just any mushroom lasagna, but Ina Garten's portobello mushroom version.
If it's a Barefoot Contessa dish, you know it's got to be good and this recipe does not disappoint. The resulting lasagna will have your guests crying, "OMG this is amazing!" It's rich, cheesy, creamy, and just plain delicious. The chunky portobellos are so meaty, even carnivores will enjoy this hearty meal. It's a one-pan dinner that's perfect for cooler weather, so get the technique after the jump.
