Butternut squash soup. Get frozen squash and bone broth simmer a bit then blend with plain unsweetened coconut yogurt. You can add curry too or season as you like. Is tasty warm or cool.

Whatever you want to eat, puree it in a blender or Vitamix with a little liquid. Hospitals and nursing homes do this all the time. Steak, roasts, veggies, salads, whatever.

This is OP: Thanks, everyone! I have been so anxious about this, and my brain was kinda short-circuiting on recipe recall.

Also, thanks to those who offered reassurance that it might only be necessary to eat mush for a few days. I hope you're right!

Cheese souffle, or Stouffer's spinach souffle if you're feeling nostalgic/lazy

Hummus

Mac and cheese, cooking the pasta really well done.

Mashed potatoes and gravy.

Just made a summer squash soup recipe and put it through a blender. If you do blend anything with seeds, like cucumber or squash, cut the seeds out first before cooking / processing.

My dh is going through this as well.

You can make different root veggie purées. I used to make one with carrots and ginger that was fantastic. Mashed sweet potatoes are good too. A light seafood bisque sounds great in this weather. And smoothies! My favorite right now is some combination of ice, milk (regular or unsweetened almond), apple, banana, almond butter, chia seeds, Greek yogurt, kale or spinach, and cinnamon.

Don't eat anything that can fall into the hole and require swishing. You can lose the clot and get dry socket.
No lentils unless you run it thru the blender. No seeds in your bread.

I had a tooth extraction last year, and IME, I only needed to eat super soft food for a few days. I ate a lot of mashed potatoes, tomato soup and fruit smoothies. It was ok to have warmish things, they just need to not be smoking hot. After a few days, I cold tolerate things like pasta, Mac n cheese, and then in a week or so, I ate pretty much everything slowly, only avoiding things like steak and tortilla chips.

Grits- cheese grits or polenta with cheese. You can also make spicy with some chili crunch. Good luck!

Cold cucumber soup is easy to make and delicious. Cucumbers, dill and yogurt.

Polenta

My favorite childhood dish is soon dubu jigae - made with soft tofu. Recipes online call for seafood, but I usually just do a vegetarian one with zucchini, onion, spinach, kelp, etc. I stew for a long time until everything is soft. And I add brown rice toward the end.
