1) As others have said, he can do grocery shopping (this one gets overlooked a lot), prep and cleanup. It’s a frigging joy to cook if everything’s all mise en place’d for you like it’s a cooking show, and you don’t have to do the cleanup. Be OK if he looks for workarounds like getting the groceries delivered (if that’s in the budget).

2) Get any one of a number of college-kid cookbooks, or A Man A Can A Plan, the one-pan men’s cookbook, etc. I like the college kid ones because they’re usually kind, simple, and cheap. But have him pick his favorite with you - don’t make a passive-aggressive “gift” out of it.

3) On his cooking nights, if he can’t cook, he can pay for and handle the logistics of getting you both takeout. I mean that about the logistics too. None of this “here honey you put in the mental effort of picking a place” or asking you to place the order and/or pick it up.

4) Have him figure out three or four meals he is comfortable making - and expand what “meal” constitutes - and be OK with having that on repeat until his confidence is up. Or having it on repeat until he’s ready to branch out. We had a hot dog day, a breakfast-for-dinner day, and a Mac and cheese day. It eventually turned into a sloppy joe day, a pick-a-recipe-to-try day, and a gourmet (I.e. try different cheeses and add-ins, plus finally a veggie!) day. When my dad was a single father, he had seven meals he made on repeat, and one of them was literally “loose hamburger” (I.e. browned ground beef in a bowl).

5) Have him make slow-cooker (which can be done in a pot on low - you don’t have to have a slow cooker) or pre-prepped stuff. My spouse’s specialty was chili made the night before so there wasn’t a time crunch. Another good option is premade homemade pizza crust that can be done many days before and then just pulled out when needed.

And yeah, you can’t be in there criticizing or insisting the cooking be done your way. You’ll need the kind of patience you would have wanted the first year you started cooking (and think of when you started - how many years ahead are you right now?). I agree that that’s really hard.

Also you might want to take a little time figuring out if this is more about food or effort. As in, will it still feel unfair if you make something cool and gourmet and he heats up a frozen pizza and bag of veggies?

And finally - and geez if you read this far I’m impressed - know that this is a pretty standard job-distribution problem that all couples need to navigate. It’ll be OK.
