The original recipe for this lasagna calls for soaking the noodles first in hot tap water.
-
14
Instead of soaking, I just rinsed each noodle quickly (about 10 seconds each) under the running kitchen faucet (hot water).
-
15
Its much easier than getting out another dish!
-
16
Spray a large casserole dish (at least 9 x 13) with cooking spray.
-
17
Evenly spread about 3/4 cup of roasted vegetables on the bottom of the dish and sprinkle about 1/4 cup of Fontina cheese over top.
-
18
Drizzle about 1/2 cup of sauce on top and place 3 uncooked (and rinsed) lasagna noodles on top.
-
19
Layer about 1 cup of roasted vegetables on top of the first layer of noodles.
-
20
Top with about 1/2 cup of Fontina and 1/4 cup of Parmesan.
-
21
Drizzle with about 1 cup of white sauce.
-
22
Top with another 3 rinsed noodles.
-
23
Repeat these layers two more times.
-
24
On top of the final layer of noodles, drizzle the remaining white sauce and top with the remainder of the cheese ... Fontina first, followed by Parmesan.
-
25
Spray a sheet of foil lightly with cooking spray so it does not stick to the cheese.
-
26
Cover the dish with the foil (sprayed side down) and bake at 400 F for 30 minutes.
-
27
Remove foil and sprinkle the top evenly with pine nuts.
-
28
Set your oven to broil and put the lasagna under the broiler until the nuts and cheese are nicely browned and bubbly (at least 5 minutes).
-
29
Make sure to watch closely so it does not burn.
-
30
Remove dish from oven and set it on a rack.
-
31
