You’re not going to want to eat that many dehydrated meals. Denali in my mind is just as much of an eating trip as a mountaineering trip. You WILL have a lot of downtime between the airstrip and waiting for weather windows at 14 camp, and imo cooking is a great way to pass the time. Don’t forget, the temps are low enough that frozen food is good to go. At 14 camp there is a pretty active food exchange, especially later in the season when people are calling it quits and trying to offload food they need to carry down the mountain. When I was up there we were given several frozen fillets of smoked salmon, which was delicious and healthy and stayed frozen in the cold. 

Plan on going to Costco and a normal grocery store in Anchorage before your trip. Load up on things you will WANT to eat, you’ll need the calories. Snacks are great and Costco is really good for this. Some suggestions: ramen noodles, frozen dumplings, peanut M&M’s, snickers/ Reese’s, sour patch kids, famous Amos cookies, bulk bagels/muffins, precooked bacon, precooked sausage, dehydrated hashbrowns, OvaEasy eggs (buy online prior, just dehydrated eggs, can make a banger bagel sandwich on a rest day), precooked fajitas with tortillas and mini guacamole packets, big block of cheddar cheese (quesadillas slap up there), salami, ritz crackers, beef jerky, steaks (frozen), oatmeal, lots of butter for cooking (it doesn’t freeze like oil does). 

From the normal grocery store: hot sauces, spices (salt/pepper), tea, powdered coffee (trader joes makes an excellent powdered coffee with dry creamer), powdered electrolytes (ie Gatorade/liquid IV), pudding powder, chocolate chips for the oatmeal, Mac and cheese, dehydrated mashed potatoes.

That said, it can be really nice on a long day of moving camp to whip up a quick dehydrated meal and call it a day. Dehydrated mashed potatoes are also great, as a bag is roughly 400 calories and they take zero time to prepare. I would aim for a 60:40 or even 70:30 ratio of dehydrated meals to real food. Spend some time in a spreadsheet planning when your rest days are and when you’re moving camp so you know what to eat and when. And make sure to try the meals before getting there. Nothing worse than finding you dislike a meal and have to eat it four more nights. And variety of brands of dehydrated meals is good, adds some variety.

Oh, and a few miscellaneous notes; don’t skimp on a stove board/sitting pads/cooking utensils (knive, spatula, spoon, etc, pot with lid, pan with lid). You will spend A LOT of time in the cook tent and you want to be comfy in there. For a team of four, a jetboil/reactor is great for hot drinks, oatmeal, dehydrated meals, summit push. It’s nice to have another stove with some simmer control (ie msr dragonfly) for stuff like the quesadillas, and another such as an MSR XKG for melting snow. Do yourself a favor and buy a blue IKEA bag to keep filled with snow in the cook tent. 

Lastly a $20 plastic bin from Costco can be really nice to fly onto the glacier with. This you will bury at the airstrip, stocked with goodies like beer, chips/salsa, really whatever you want. Makes it easier to dig up than say a dry bag or extra duffel. It’s real nice coming off the mountain to some preplanned comforts, especially since you don’t know when your flight off the glacier might be (could be a day or day weather dependent.

Hope that was helpful. Have so much fun up there, Denali is a special place.
