So you're going to start meal prepping (maybe with the help of this 30-day meal-prep guide for beginners). Go you! But now you need meal-prep containers—and you may not know where to start. Should you invest in expensive glass meal-prep containers? Or is it okay to use leftover takeout containers? And how many do you *actually* need to buy?

We chatted with a meal-prep pro to find out answers to these questions and more—because your meal prep is only as good as the containers it's in, right?

Plastic vs. Glass Meal-Prep Containers

One of the biggest debates in meal prep is whether it matters what material your containers are made from. Plastic and glass are the most common choices. The answer? It depends on your priorities.

"Glass meal-prep containers are obviously better for the environment, but when it comes to our bodies, both are safe if you know what to look for," explains Talia Koren, founder of Workweek Lunch. (Speaking of things that are good for the environment—consider investing in these eco-friendly products on Amazon that will help reduce your daily waste.)

"Plastic containers that are BPA-free and made for food storage are totally safe to use and put in the microwave," she says. Food-safe containers will have the number 1, 2, 4, or 5 on the bottom. This indicates the type of plastic used to make the container. If a container has 3, 6, or 7 on the bottom, it's not safe to use.

BPA-free plastic containers only become unsafe when they're cracked; then it's time to throw them out, says Koren. Personally, Koren says she prefers plastic because they're more budget-friendly, lighter, and easier to carry around. "They're also easier to store and if you drop them, they won't break!"

However, glass is ideal if you're frequently reheating meals in the oven, she adds. You don't need to transfer your food to a new container to reheat it, the way you need to with plastic. Bonus: They're also less likely than plastic to stain, says Koren.

Stainless steel is also an option (it's actually Kourtney Kardashian's meal-prep container material of choice), but it can be a pricier (and non-microwave-friendly) choice.

How Many Meal-Prep Containers Do You Need?

Many people are unsure of exactly how many meal-prep containers they need when they're first getting started. Ultimately, it depends on how many meals you plan to make ahead of time. Try starting with six containers, says Koren. That should be plenty to work with if you're not prepping every single meal.

"With six containers, you can do five lunches or a couple lunches and dinners for the week," she explains. If you're planning to prep three meals a day for five days, though, you might want to consider grabbing a few more. (Heads up: Here's how to pick the perfect meal-prep recipe.)

Meal-Prep Container Layouts and Sizes

There are many different size and shape options out there for meal-prep containers, but what's most important is that they fit the meals you want to prepare and fit into your fridge or freezer easily.

"Start with cheaper containers because it might take some time to figure out which size is best," suggests Koren. "I started with 40-oz containers, which were way too big. Now I use 25-oz (about 3 cups) containers and they're perfect. You have to experiment to find the best size for you!" (If you're just getting started, read up on these meal-prep mistakes to avoid for faster, healthier, and better food.)

And while single-compartment meal-prep containers work just fine for most people, bento-style boxes do have their advantages. "If you're someone that likes to keep veggies separate from your protein, the containers with compartments are great. They're also good for the times you want to reheat part of a meal, but not the whole thing, or want to keep salad ingredients separate to avoid sogginess."

Reheating, Freezing, and Washing Your Meal-Prep Containers

Not all containers have the same rules for reheating, washing, and freezing. "When you're buying containers, it will say on the package how to wash them properly and if they can be frozen," says Koren. The package should also explain which heat methods are safe.

In general, most glass and plastic containers can be put in the dishwasher and microwave. "The only time it's not safe to do that is with plastic containers you get from takeout places; they're not microwave- or dishwasher-friendly and they shouldn't be reused to store food." (These types of containers aren't meant for reuse, so they aren't made according to the same safety standards as reusable plastic containers.)

Hi, my name is Kate and I would like to share my story. Up until about 2 years ago, I was 30 pounds overweight. Over the years I had followed many different diet plans, but failed every single time. I was "blessed" with a pear shaped body and no matter what i did, I always retained lots of stubborn fat in my lower body. Everything changed when I found the right diet program.

Hello everyone, I must start by saying that I didnt go into marriage with expectation that it will fail after 8 years. I and my spouse where not compassionate to ourselves. Trying to work out my marriage was self-defeating, we dont really know why we no longer find ourselves attractive anymore. All we secretly thought was divorce, we couldnt agree or communicate anymore, it was emotionally difficult moments when we face each other in the bedroom. I know that a phycologist might not be able to help me go through divorce because it has never worked for me. Divorcing could traumatize our kids, I cant let them be emotionally crippled. I remember my grandmother once told me that not issues can be resolved physically, I should try solving some issues spiritually through a well-known spiritual doctor. I can provide evidence that my life and marriage got more better and interesting with so much love and fulfilled promises after Dr. Wakina lighted up our fire with a magnificent love spell with the aid of The spell work I never regarded rewrote my story. Im touched beyond words, thanks Dr. Wakina.
