12 Vegetable Side Dishes

Twelve sides where the vegetable is the point rather than the garnish, from a tray of sprouts to two arguments about sweet potato casserole.

Four vegetable side dishes on a dark wooden table: a bowl of roasted Brussels sprouts with balsamic glaze in front, with whole roasted rainbow carrots, creamy coleslaw and a chopped pepper, cucumber and tomato salad behind.

A side dish is the thing you decide last and regret first. Everything below is a dish where the vegetable is the main event rather than a bed for something else, so any one of them can hold a plate next to a plain main.

What is here

Three trays of roasted vegetables, three casseroles, two mashes that do completely different jobs, and four bowls that need no heat at all. Both sweet potato casseroles are here because the marshmallow question splits households and nobody arrives at it undecided.

Cooking more than one of them

Two things collide on a real table and both of them are the oven. The roasted dishes want 425°F and the casseroles want 350°F, so a menu built from three of these is easiest when one of the three is cold. The second collision is the last ten minutes, which the sprouts, the carrots and both casserole toppings all want to themselves. That is the argument for putting one of the cold bowls beside whatever you roast.

1.Brussels Sprouts

Roasted Brussels sprouts on a cream plate, the cut faces browned to deep mahogany, drizzled with a thin balsamic glaze and dusted with finely grated Parmesan.
Vegetarian: yes
Vegan: no
Gluten Free: yes
Dairy Free: no
40 minutes 4 servings

Roast sprouts on a cold sheet in a crowded pan and they come out pale and soft, which is where most people's opinion of the vegetable came from. Preheat the sheet and give them room and the flat cut faces brown into the thing people go back to the kitchen for.

Watch for: The loose leaves that fall off and go dark on the pan are not a mistake. They crisp up like kale chips and they are the best thing on the tray, so leave them where they are.

2.Vegan Mashed Potatoes

Vegan mashed potatoes swirled into soft ridges in a deep blue stoneware bowl, golden and smooth, scattered with snipped chives and cracked black pepper.
Vegetarian: yes
Vegan: yes
Gluten Free: yes
Dairy Free: yes
40 minutes 6 servings

Mash with no dairy to hide behind, which is where most versions quietly come apart. The seasoning is the part people skip: a potato takes up salt only while it is cooking, so an unsalted pot cannot be rescued at the end however much you beat into it.

Watch for: Cold oat milk straight from the fridge drops the temperature of the whole pot at once and tightens the mash before it reaches the table. Warm it first.

3.Rainbow Carrots

Roasted rainbow carrots on a white platter, purple, orange and gold halves caramelized and glazed with honey, scattered with chopped thyme and parsley
Vegetarian: yes
Vegan: no
Gluten Free: yes
Dairy Free: yes
50 minutes 4 servings

The cheapest way to make a plate look composed, once you know what the color costs, because the purple ones bleed into whatever they are tossed with. It also needs a squeeze of acid more than anything else here, since roasting and honey push in the same sweet direction.

Watch for: A rainbow bunch is nothing like a uniform bag of orange carrots. Cut the thick ends down to match the thin ones or half the tray is mush before the rest is tender.

4.Vegan Cole Slaw

A bowl of vegan cole slaw with cabbage and carrots, garnished with herbs, on a picnic blanket.
Vegetarian: yes
Vegan: yes
Gluten Free: yes
Dairy Free: yes
45 minutes 6 servings

Crunch and acid next to anything roasted or baked, and no oven time at all. It sits beside a burger in July as readily as it sits on a buffet in November, which is a longer season than most sides get.

Watch for: Cabbage keeps giving up water after it is dressed. Half an hour in the fridge is the point of the recipe, but half a day and the dressing is a puddle at the bottom of the bowl.

5.Mashed Cauliflower

Creamy mashed cauliflower in a speckled stoneware bowl, swirled thick and pale and scattered with snipped chives and coarse black pepper, a whole cauliflower and garlic bulbs on the table behind.
Vegetarian: yes
Vegan: no
Gluten Free: yes
Dairy Free: no
25 minutes 4 servings

Lighter than potato mash, quicker by a wide margin, and better under anything with a sauce on it. What decides whether it works is how much water the cauliflower is still carrying when it goes into the processor.

Watch for: A food processor ruins mashed potatoes and is exactly the right tool here. There is no potato starch to rupture, so the caution you brought over from mash does not apply.

6.Vegan Green Bean Casserole

Vegan green bean casserole in a cream stoneware baking dish, cut green beans and sliced browned mushrooms in a thick tan mushroom sauce under a heaped layer of deep golden crispy fried onions.
Vegetarian: yes
Vegan: yes
Gluten Free: no
Dairy Free: yes
1 hour 20 minutes 8 servings

Most households make this from a can and a packet, so a version built from scratch has to earn the extra hour. It earns it on the beans, blanched fresh and still squeaking, instead of the gray mush the dish is known for.

Watch for: The crispy onions go on at the end, not at the start. They have been fried once already, so a full bake turns them dark and bitter while the middle is still warming through.

7.Veggie Salad Without Lettuce

A colorful salad with cherry tomatoes, cucumbers, diced bell peppers, red onions, topped with parsley, on a rustic table.
Vegetarian: yes
Vegan: yes
Gluten Free: yes
Dairy Free: yes
10 minutes 4 servings

For the nights when the oven is full and the side has to be finished in the time the main takes to rest. No leaves means nothing to wilt, so it also survives a car journey and a folding table better than a green salad does.

Watch for: Dress it as it goes out. Salt pulls water from cucumber and tomato within minutes, and a bowl that has stood dressed for an hour is vegetables sitting in diluted lemon juice.

8.Sweet Potato Casserole with Pecan Streusel

Sweet potato casserole in a white baking dish, a golden pecan streusel crust with one square lifted out to show the dense set orange filling underneath.
Vegetarian: yes
Vegan: no
Gluten Free: no
Dairy Free: no
2 hours 20 minutes 8 servings

For a table where somebody has already said no marshmallows. The streusel is the reason to make it and also the part that fails: it needs enough soft butter to clump, or it bakes into loose sand and slides off the first serving spoon.

Watch for: Let the roasted flesh cool before the eggs go in. Egg meeting hot potato cooks on contact and leaves yellow threads through the filling that nothing takes back out.

9.Mediterranean Roasted Vegetable Salad

A vibrant Mediterranean roasted vegetable salad with bell peppers, zucchini, eggplant, and feta cheese on a wooden table.
Vegetarian: yes
Vegan: no
Gluten Free: yes
Dairy Free: no
45 minutes 4 servings

A tray of roasted peppers, zucchini and eggplant that becomes a dish rather than a component once it meets the greens. It is as good at room temperature an hour later as it is straight off the sheet, which makes it the easiest one here to cook for a crowd.

Watch for: Let the vegetables stop steaming before they meet the greens. Straight from the oven they collapse the leaves into the bottom of the bowl.

10.Vegan Caesar Salad

A fresh Vegan Caesar Salad with romaine lettuce, croutons, and creamy dressing on a wooden table.
Vegetarian: yes
Vegan: yes
Gluten Free: no
Dairy Free: yes
20 minutes 4 servings

A green salad that behaves like a side rather than a bowl of leaves, because the dressing is thick enough to coat instead of running to the bottom. Put it next to something heavy: it reads rich without putting more dairy on the table.

Watch for: The dressing stiffens in the fridge as the cashews keep drinking. Beat water back into it a spoonful at a time before it goes near the lettuce, or it tears the leaves instead of coating them.

11.Sweet Potato Casserole with Marshmallows

Sweet potato casserole in a white baking dish on a candlelit holiday table, deep orange baked sweet potato under a layer of golden toasted mini marshmallows, with one serving scooped out to show the set layers
Vegetarian: yes
Vegan: no
Gluten Free: yes
Dairy Free: no
2 hours 15 minutes 8 servings

The one people remember from childhood, and arguing with it is a waste of a good holiday. What keeps it a side dish rather than a dessert is restraint with the sugar, since roasting the potatoes has already done most of the sweetening.

Watch for: Vegan marshmallows hold their shape instead of slumping into a sheet, since gelatin is what does the melting in the conventional ones. Nothing has gone wrong, but do not wait for a spread that is not coming.

12.Marinated Vegetable Salad

A vibrant marinated vegetable salad with cherry tomatoes, cucumbers, bell peppers, and parsley on a wooden table.
Vegetarian: yes
Vegan: yes
Gluten Free: yes
Dairy Free: yes
45 minutes 4 servings

Almost the same vegetables as the lettuce-free bowl further up, dressed and then left alone, which turns out to make a different dish. Time in oil and vinegar takes the raw edge off the onion and the pepper, and it is the one thing here that is better made the day before than the hour before.

Watch for: The vegetables give up water into the dressing while they sit, so it thins as it works. Taste it again before it goes out and put back the salt and the acid it has lost.

Frequently Asked Questions

  • Which of these can I make ahead?

    The cold ones split two ways. The marinated salad and the slaw are better for a night in the fridge; the lettuce-free salad and the Caesar are worse for it, because dressed cucumber and dressed leaves both start shedding water within the hour. Of the hot dishes, the three casseroles can be assembled a day early and baked from cold, which costs about ten extra minutes in the oven and buys back the whole of the last hour.

  • How many sides do I need?

    One on a weeknight. For six people or more, three is the number that stops a table looking thin, and the split that works is one roasted, one starchy and one raw. Two roasted trays and a mash reads as heavy by the third plate.

  • Can I roast two of these at the same time?

    Yes, on two sheets on two racks, swapped halfway through. Not on one sheet, and that is the single most common reason roasted vegetables come out pale: crowded, they steam in the water they release instead of browning in dry heat. If a casserole needs the oven at 350°F at the same time, roast first and let the tray stand. Roasted vegetables are fine warm and poor reheated under foil.

  • Which ones travel to a potluck?

    The marinated salad and the slaw go first, because sitting in dressing is the job they were built for. The casseroles travel well and reheat covered. The two mashes are the ones to leave at home: both stiffen as they cool, and neither comes back to the same texture in somebody else’s microwave.

  • Are they vegan?

    Several are, and the badges on each entry say which without opening the recipe. Where one is not, a single dairy ingredient is usually the thing in the way: cream cheese and butter in the cauliflower mash, cream in the pecan streusel casserole, feta on the roasted vegetable salad, Parmesan on the sprouts. That last one is worth reading twice on a vegetarian table, because real Parmigiano-Reggiano is set with calf rennet.

  • What is the difference between the two sweet potato casseroles?

    The topping, and then everything the topping drags along with it. The marshmallow version is the 1917 original and lands closer to dessert, which is why the sugar in the base is kept low. The pecan streusel version is drier, saltier and firm enough to cut into squares, so it holds a shape on a crowded plate. Households tend to have strong feelings and no interest in the other one.
