Simple question … poll to follow!
Alternating layers of ragu alla bolognese and besciamella, with freshly made spinach pasta sheets. ETA: And of course, sprinkled with Parmesan Reggiano or Grana Padano on each layer.
I haven’t even heard of putting chicken in a lasagna dish.
Sounds pretty good, and the spinach version is good as well.
My recipe includes sausage, spinach, onions, and olives, in addition to the standard noodles, tomato sauce, assorted cheeses, and garlic and other assorted herbs.
Meat lasagna (specifically excluding this “chicken” nonsense) and spinach lasagna are the only true forms of the dish.
Mine isn’t easily summarized with the available options, so I said other.
I use my spaghetti sauce, which is made with ground beef, onions, diced tomatoes, mushrooms, tomato paste, spices, and a splash of wine. My cheese layer may or may not have spinach in it, depending on my mood. I may also layer sliced mushrooms between the cheese and sauce layers. I’ve also made it with conventional lasagna pasta or with pasta shapes (tastes the same, easier to serve) and I always top it with lots of mozzarella. I’ve also used shredded carrots mixed in with the cheese.
As it happens, I’ll be building a lasagne next week - it’ll be big enough for 3 meals at least. 
I once had a recipe for a vegetarian lasagna that I got from a veggie girl I dated. It was excellent. However, being a serious carnivore*, I later added meat to the mix. It turned out to be unnecessary. But I love a good meat lasagna, too.
So, I checked both “meat” and “veggie”, but not “meat and veggie”.
- But, hey, if going veggie temporarily would get me laid, what the hell…
I made a lasagne with chicken pesto sausage once. It was for a friend who didn’t eat beef or pork. It was ok, but I haven’t had the urge to repeat it.
I said meat & veggies. I use some ground beef, sausage, veggie crumbles, zucchini slices and spinach. Sometimes all of the above, sometimes just a few.
Quattro formaggi. No meat.
Meat ragu of some sort, cheese, pasta. Said cheese must include some sort of ricotta/cottage cheese layer, as well as a melty cheese or three.
Spinach can be tolerated, but doesn’t add much. Bechamel is verboten. Bechamel-based lasagnas are the invention of one of Satan’s lesser imps.
I picked with veggies, but I really only want mushrooms. Spinach is tolerable, other vegetables are unwanted. Meat is ok, but not that much of an improvement over lasagna the way my mother made it.
It’s not so much that she made really good lasagna, as that she made the lasagnas that defined lasagna in my brain.
I like Tamerlane’s version, with some 'shrooms, which must be very finely chopped for textural reasons. But lasagne is a lot like sex and pizza: even when it’s bad, it’s pretty good. IMHO and all that jazz.
Target’s Archer Farms brand used to make a Southwest Style Lasanga that was basically Enchilada Lasagna. Loved Loved Loved it. Corn Tortillas instead of pasta, corn, blackbeans, peppers, meat and cheese in enchilada sauce.
Then damn them, they had to stop making it.
I like a very simple version with just pasta, seasoned ground beef and/or sausage meat, sauce and mozzarella, sprinkled with grated parmesan. I don’t do ricotta, which I realize some may consider blasphemous, but I just don’t like it.
Since I am a vegetarian, meat is out. My favorite is the all cheese kind, the more cheese the better, (with garlic bread of course) but the kind with lots of veggies in it can be good too.
Where’s the bechamel and seafood option?
I like spinach or meat. I had a roommate once who made lasagna for us to share and she put sliced carrots in it. She seemed to be under the impression that that was a legitimate lasagna option.
we like it pretty much any way that does not include mushrooms, okra,zucchini or eggplant. i have had killer vegan, killer vegetarian and killer carnivore versions. The one I didn’t really like that friends liked was the Japanese fusion one with nori and tenticular critters. I am a bit more traditional than that [well actually I hate seaweed and squid/octopods and will at least try anything that doesn’t include stuff I am actually allergic to on the odd chance I might like whatever in this new application.]
I like it all ways. I used to make it with ground turkey. That’s pretty good too.
I’m not sure I even have a favorite. However, I do think I’ll go get some for tonight.
