I use a frozen pasta sheet. I can thaw or start frozen. Many will tell you to get a fresh pasta sheet if at all possible, and I( agree if it is affordable and practical. No options here in south Coweta County GA
I use 4 pasta sheets and three layers of filling. It is not a heaping lasagna; it fills a 1/4 size 2" deep (I think) pan. Mine is somewhat dense, and creamy when done. I use
1.25 lb ricotta (1 whole egg usually)
.5 cup parmesan
1lb + 1 cup mozerella
(plus 1 lb mix of cooked beef/sausage for meat lasagna)
sauces and such
I get 9 servings out of this pan. Food cost last fall (I haven’t done it in new location yet) for meat lasagna plus salad and bread is
ONLY 17.5%. That’s with a pre-made, frozen lasagna sheet. Sure, my costs have gone up, but with a small selling price increase, I am certain I can keep it no higher than 20%. It delivers well, holds well, and REHEATS WELL. I make a couple pans up at a time, under cook slightly and freeze portions. I keep a few thawed all the time (weekends a few extra), and microwave to reheat for something like 7 minutes . . . add sauce, and it is delightfully like fresh out of the oven. Even frozen, I can reheat in the microwave for a couple minutes more. Get to know your microwave if you use it. Know how to use settings other than 100% power, and you will score.
I used to do only cheese lasagna and sell with red sauce or meat sauce. that went over very well, but customers kept asking for a meat lasagna. So, I gave it to them, and it took off.
I can send you my excel sheet recipe if you’d like to see what you think of it.
