Some great make-ahead vegetable side dishes will save your sanity during busy holiday seasons. Holidays like Thanksgiving and Christmas are the perfect time to use them, but they’re great for Easter, and potlucks too.

As moms, we are all super busy. Too busy to try and make 15 dishes all in one day … and that’s exactly why make-ahead side dishes are perfect. You can easily prepare a couple of side dishes on the weekend or an evening ahead of time and then just warm them up on the serving day.
The following recipes are all fancy enough for Thanksgiving or Christmas, but also simple enough to have any other day of the year. They can be used for your weekly meal prep, too.
What to Store Make-Ahead Side Dishes In
- Use an oven-safe casserole dish – if you want to go straight to the oven.
- Store them in a plastic or glass storage container – you can reheat in the glass and transfer to a serving dish if you want to.
- Put them directly into your slow cooker liner – this may take up a lot of space in the refrigerator but will save on dishes and time when you go to reheat.

Oven, Microwave, Freezer Safe Dishes
All of these dishes can go straight from the refrigerator or freezer to the oven or microwave. Keep in mind, the colder your side dish, the longer it will take to heat up. Also, if you want a crumb topping or crust on the top, you won’t be able to stir the dish in order to distribute the heat. It will take much longer to warm all the way to the middle.
How to Reheat Your Side Dishes
When it’s Thanksgiving, Christmas, or any other Holiday, oven space is at a premium. I like to use the microwave to reheat most of the side dishes that I’ve made ahead of time.
It can easily take an hour to reheat them in the oven. I also like to use my slow cooker whenever possible. This makes them almost hands-free to reheat.
The microwave or slow cooker is best to use because I want to stir things up while reheating. If I want the final dish to have a topping, I add it to the top once it is warm throughout. Then I put it in the oven to allow the top to brown and crisp up.
