Any suggestions for make-ahead vegetable dishes that don't involve dairy?

Several packages of frozen petit lois; cook according to instructions, add a little butter and salt. Reheat and garnish with fresh chopped mint (or just skip that step).

petit lois or petit pois?

Not sure whether these candied carrots will take up too much time, but they are delicious.

^^ Sounds great but maybe for another time.

Damn this question. Craving carrots now. That can’t be normal.

I make delicious chopped potatoes with onion soup mix in the crock pot. Just chunk up your potatoes and pour 2 cups onion soup over them and let them cook on high for about 3 hours. Mmmm good.
Also baked cabbage with olive oil, S&P and Italian seasonings and zucchini and yellow crookneck squash sauteed with lite non-dairy butter spread, S&P and Italian seasonings.

Both are easy and delicious and only need reheating in the microwave.
I JUST warmed up a bowl of the potatoes and squash for my lunch.

Thanks. The potatoes will be roasted though.

@janbb: Typing in bed with bifocals.

@gailcalled Almost as much fun as “Waltzing with Bears.”

Cold veggie pizza with non-dairy cream cheese?

Looks delicious.

Root vegetables roasted with honey and Balsamic vinegar. Can be served at room temp just fine if need be.

Roasted Asparagus drizzled with olive oil and mixture of salt, pepper, sugar.

Again, works well at room temp.

I sauté fresh green beans in oil with a little garlic (very little) and some salt. I like them crisp in the middle so I cook them just enough and that’s it. They still taste good the next day, and green beans are a typical food on Thanksgiving, they just usually are in the casserole that’s the only difference.

You could in the same sauté pan afterwards fry up some onions with a little salt. I’d slice the onions very thinly, and sauté to quite a toasty brown. Serve the onions over the beans. The other choice is the store bought French’s onions used in the casserole. Toast them in the oven (watch you don’t burn them) and serve on top of the beans. I’m not sure if the packaged onions are non-dairy, so you would just have to double check. They seem like they would be. I never bother with onions myself for green beans, but I thought it might help make it seem more like the traditional Thanksgiving beans.

Any roasted or grilled veggies and just microwave them a bit before serving them the next day. Eggplant, zucchini, mushrooms, asparagus, bell peppers, and onions to name a few.

I just thought to google parve side dishes. The herb mushrooms with wine look good on this site and there are many other dishes.

Agree with @Buttonstc – roasted root vegetables is my favorite (although I drizzle maple syrup and olive oil with sea salt, turmeric and a bit of something spicy like chili powder).

Baked kale chips and sauteed garlicky greens are both yummy.

I roast green beans at 400 degrees until caramelized and then pretend they are french fries while I eat them.

You could also make a white sauce with a milk substitute of your choice to sub in for cream of anything soup… or try canned coconut milk.

My kids are nuts about this, so I would consider it kid-approved:
Cut a bunch of Brussels Sprouts in half
Steam for 6 min.
Stir fry them in garlic and olive oil until they just start to brown

We never have any left after dinner.
