The other day I saw a recipe for sweet potato lasagna online that looked good and would also be an excuse to use my Vegetable Sheet Cutter, so I uploaded it to my recipe planner, thinking I might make it and share it here if it turned out well.
A few days later I opened up the recipe and actually read the ingredients and, in what seems to be an emerging pattern, immediately changed everything about it and made a completely different thing. At least it still has sweet potatoes.
In all fairness to me, the original recipe contained tofu and nutritional yeast, a combination that I had a Very Bad Experience with once. I’m not vegan, so I’m gonna leave that trauma in the past where it belongs.
The other thing is, the recipe wanted me to make sauce from scratch. I get it; lasagna is kind of a big deal thing that grandma made and it can be very special. But most of the time my M.O. with cooking is to streamline things as much as possible. There are so many great organic jar sauces available now, so I say save the extra work for a weekend when you have access to good tomatoes.
In the end, I didn’t use the Vegetable Sheet Cutter. I had very large sweet potatoes and it looked like it was going to be a battle to get the skewer through them, and I was afraid of damaging the attachment or skewering myself. The next best thing would be the mandoline, but I hadn’t used mine in a long time (confession: I’m afraid of it) and discovered it was broken. I ended up slicing the potatoes with a trusty chef’s knife. Alton Brown would approve of my lack of gadgetry. That said, I’d recommend the mandoline because you’ll need to get the potatoes very thin.
Note: You can use an egg in the filling. Since we have the egg allergy, I used VeganEgg egg substitute.
Easy Sweet Potato Lasagna
VeganEgg egg substitute (recipe for 1 egg), or 1 large egg, beaten
16 ounces shredded mozzarella, divided
15 ounces ricotta
Pinch of grated nutmeg
3 cups baby spinach leaves
1 pound ground beef
1 32-ounce jar of marinara sauce
8 ounces sliced button mushrooms
Italian seasoning (optional: I like Penzey’s Tuscan Sunset)
Freshly grated Parmesan
2 very large or 3 medium white sweet potatoes, sliced thin
Preheat oven to 350 degrees. Lightly oil a 13×9-inch baking dish with olive oil.
Mix the egg substitute. (I use a blender.) In a food processor combine the egg substitute, ricotta and 8 ounces of shredded mozzarella. Grate in a pinch of nutmeg. Process until just combined. Add baby spinach and process until all the spinach is chopped, but don’t overprocess.
In a large skillet, brown ground beef, breaking into small pieces. Add sauce and mushrooms and cook over medium heat until mushrooms are cooked but not overcooked. Sprinkle in Italian seasoning if desired.
Spread a thin layer of marinara sauce on the bottom of the baking dish. Cover bottom of dish with a layer of sweet potato slices. Top with a layer of spinach mixture, followed by a layer of the marinara mixture. Repeat with remaining layers. Top last layer of marinara mixture with remaining shredded mozzarella.
Cover with nonstick aluminum foil and bake for 1 hour. Uncover and increase heat to 400 degrees for 15 minutes or until cheese is melted and lightly browned. Allow to cool for 15 minutes before slicing and serving.
