What kinds of recipes work for this?

This is a fantastic question that I get a lot.
Most marinades work great for this type of cooking.
Some casseroles do work and others do not. Some casseroles that appear not to work can be altered to work.
For example - for most recipes that require pasta to be cooked before freezing - don't cook the pasta. When I do a freezer lasagna, I put in regular, uncooked lasagna noodles. I don't use the "no-boil" choice - they are too expensive; I use the regular regular lasagna noodles. Yes I will add a tad bit more liquid/tomato sauce, but mainly I will just do a bit more cooking time.
For a recipe with rice that has to be cooked before adding, undercook it slightly - may be 5 minutes. This will make it a bit tough, but after freezing and defrosting then cooking in the oven, it will be perfect. If you have already cooked it the right length of time, based on the bag/box prep information, you may end up with mushy rice after freezing, defrosting and cooking in the oven.

Now for marinades - meat that is tough, like flank steak, work great in this type of cooking. You will end up with the most tender, delicious meat you have ever had and it won't be so over marinated that you can't taste the food. The meat will marinate while you freeze it and while you defrost. In addition, it will sink into the fibers of the meat and really tenderize without you having to use a tenderizer mallet!

Now here's a great, easy marinade for Carne Asada:
3-4 pounds New York or Flank steak
1 cup prepared Italian dressing
1 cup Corona beer
2-3 tsp of crushed red pepper (add more if you like it spicer!)
2-3 cloves, crushed garlic
1/4 cup lime juice
salt and pepper, as desired

1. Place steak in 1 gallon freezer bag
2. Add all remaining ingredients
3. Seal bag, shake to combine and freeze. If you don't want to freeze, allow this to marinate 4 hours or over night.

When ready to prepare- defrost completely and remove steak from marinade; discard marinade. Preheat barbecue and cook until desired doneness is achieved.
Serve with flour tortillas and cheese.
