Do you ever get the urge, at 6:30 pm on a weeknight when everyone is already starving, to whip up something markedly not weeknight appropriate? Say, lasagna for instance? I did. Last night. I simply turned a blind eye while my hungry counterpart stole nibbles of shredded cheese from the counter for himself and our furry companion, and everyone was happy when dinner finally made it’s appearance two hours later.
On a rainy Fall night, when you aren’t quite sure how you feel about November showing up unexpectedly and without permission, there is nothing like a piping hot lasagna to cheer you up, with a thick layer of chewy cheese on top and crunchy edges. And let me tell you – roasted eggplant and portobello mushrooms make a killer lasagna. I surpassed my own self-expectations with this one.




If you’re an eggplant fan, don’t miss my grilled eggplant with garlic oil and whipped feta.

Roasted Eggplant and Portobello Mushroom Lasagna
Ingredients
- 1 box oven-ready lasagna noodles
- 2 cups ricotta or cottage cheese
- 6 oz spinach about 6 cups
- 1 lb mozzarella cheese shredded (makes 4 cups)
- ½ cup Parmigiano Reggiano optional, do not substitute the powdery parmesan cheese
- 1 recipe Marinara Sauce below
- 1 recipe Roasted Eggplant and Portobello Mushrooms below
Basic Marinara Sauce
- ¼ cup olive oil
- 1 large onion diced
- 5-6 cloves garlic minced
- 2 tbsp tomato paste
- 4 cups diced canned tomatoes
- Salt
Roasted Eggplant and Portobello Mushrooms
- 1 large eggplant or 2 small ones
- 2-3 portobello mushrooms
- ¼ cup olive oil
- Salt
Instructions
- Preheat the oven to 400 degrees. Mince spinach in a food processor, then stir in ricotta or cottage cheese. Set aside. Spread about 1 cup of marinara sauce in the bottom of a 13" by 9" baking dish, and arrange 3 lasagna noodles over top. Spread another 1 cup of sauce over noodles, and add half of the roasted vegetables and 1/3 of the cheese. Top with 3 more noodles, then the spinach/cottage cheese mixture. Repeat with another layer of sauce, vegetables and cheese. Top with noodles, the remaining sauce, the remainder of the mozzarella, plus the parmagiano reggiano, if using. Bake uncovered for 35-45 minutes, and let rest 10 minutes before cutting.
- Heat oil in a large saucepan over medium-high heat. Saute onion until translucent, about 5 minutes. Add garlic and saute 2 minutes. Stir in tomato paste and canned tomatoes. Simmer 20 minutes, uncovered. Puree sauce with an immersion blender, or in batches if using a regular blender. Season well with salt, tasting as you go.
- Preheat broiler, and arrange a rack at top of the oven. Slice eggplant into 1/4 inch rounds. Sprinkle generously with salt on both sides, and layer in a colander. Let eggplant sit for at least 15 minutes, then rinse with cool water and dry well with paper towels.
- Slice portobello mushroom caps into 1/3 inch strips. Coarsely chop stems. Toss mushrooms and eggplant with 1/4 cup oil and arrange in a single later on a baking sheet. Broil until soft and charred, flipping after about 6 minutes and cooking about another 3 minutes on the other side.
