Reviews of The Best Overnight Containers

1. What’s in My Kitchen: Weck Mold Jars

My go-to containers for overnight oats are Weck jars—specifically the 12.5-ounce size, which come in a set of six. The jars are also available in several other sizes if you like larger or smaller portions. These containers are great because they have a wide opening that’s easy to eat out of, and the jars can be stacked on top of each other in the fridge. This makes it easy to prepare a few days’ worth of breakfast in advance.

Weck jars are microwave-safe, in case you like your oats warm, and they can be cleaned in the dishwasher. I also love that you can buy replacement rubber seals for the lids, so you can use them for years as long as the glass is in good condition. 

The Specs:

• Capacity: 12.5 ounces
• Material: Glass
• Lid Style: Clamps
• Dishwasher Safe: Yes

The Pros:

• Wide jar openings

The glass containers are the perfect size for a single serving of overnight oats, and they’re leakproof when the lids are put on tightly, making them easy to take on-the-go and eat in the office or at school.

If you tend to grab breakfast while rushing out the door, the Bentgo Snack Cup is a smart solution for transporting overnight oats.

The larger bottom compartment, which holds 16 ounces, is where you’d put your oats, and the smaller upper compartment can be used to store toppings like fresh fruit until you’re ready to eat it. The cup can even be microwaved, in case you prefer your snack warm.

Other Overnight oat Containers to Consider

Rubbermaid Brilliance Food Storage Container

If you prefer plastic containers, which are a bit more durable than glass, the Rubbermaid Brilliance Food Storage Containers are a top choice. They come in a few different sizes, and the lids seal tightly to prevent spills. These containers also stack nicely to save space in your fridge. The Rubbermaid Brilliance Food Storage Container is available at Amazon for $9.99.

S’well Glass Prep Bowls

These bowl-shaped containers come in a pack of four, and the shape of the bowl makes them easy to eat from. They also fit perfectly in the brand’s Stainless Steel Food Bowls for added insulation. The glass jars can hold up to 12 ounces of food, and they’re microwave and dishwasher-friendly. The only downside is that they don’t stack, so they might take up a little too much space in your fridge. The S’well Glass Prep Bowls are available at Amazon for $28.

Anchor Hocking TrueSeal Glass Food Storage Container

You can buy these glass storage bowls individually or in sets of six, and they have a 2-cup capacity that’s ideal for larger portions of oats.

Williams Sonoma Breakfast Overnight Oats Jar

These cute jars were designed specifically for overnight oats. They’re made from BPA-free plastic that’s shatter-proof, and each jar comes with a snap-on lid for storage. The containers have an 18-ounce capacity and are dishwasher safe, but they are more pricey than many of my other favorites. The Williams Sonoma Breakfast Overnight Oats Jar is available at Williams Sonoma for $22.95.

Why You Can Trust Me

I’m Yumna, and I started Feel Good Foodie more than 10 years ago with the goal of making healthy cooking easy. To date, my Easy Overnight Oats is one of the most popular recipes on this site, and it’s a personal favorite, as well. I love that the recipe doesn’t require any cooking, and it’s easy to adjust the ingredients to suit your personal tastes. I also love oats so much that I created Oath, my premade overnight oat mixes that are super easy and delicious

Many of the containers I highlighted on this list are ones I’ve personally used, but I also researched other highly-rated products to round out the list. There are lots of great containers out there today, so you’re sure to find an option that fits your needs. 

Everything to Know Before Buying an Overnight Oats Container

What to Consider Before Buying an Overnight Oats Container

There are a few different things you’ll want to think about as you compare different containers for your overnight oats:

Size: I personally like my overnight oat containers to hold around 12 ounces—roughly 1.5 cups. However, you may want to look for larger or smaller containers, depending on your preferred serving size. 

Material: Most containers are either made from glass or plastic, and there are benefits to both. Glass won’t stain and is safe to microwave, while plastic tends to be lighter and less fragile.

Shape: Jar-shaped containers are tall and skinny, which means they’ll take up less space in your fridge, but bowl-shaped products are often easier to eat out of. You may also want to look for containers that can be stacked for more compact storage. 

Leakproof: If you plan to take your overnight oats with you in the morning, you’ll want to look for leakproof containers. Rubber or silicone seals will help ensure nothing spills in your bag during your commute. 

What Size Container Do You Need for Overnight Oats?

I personally like to make overnight oats in 12-ounce containers, which are just the right size for my recipe. However, 8- or 16-ounce containers can also be used if you want to increase or decrease your portion size. 

Can You Make Overnight Oats in a Plastic Container?

You can definitely make overnight oats in a plastic container. Plastic jars tend to be more durable than glass, especially when dropped, making them a popular choice for families. They’re also lightweight and inexpensive. Just be sure the container you choose is made from BPA-free plastic, and double-check that it’s safe to put in the dishwasher and/or microwave. 

Should You Use Mason Jars for Overnight Oats? 

Mason jars are one of the most popular containers for overnight oats, but they’re certainly not the only option. Many people like these jars because they’re inexpensive, but there are plenty of other containers that work just as well, including all of the products I’ve recommended above. 

How Long Do Overnight Oats Need to Sit? 

I recommend letting your overnight oats sit for at least two hours, which will give the oats time to soften and the chia seeds to plump up. Most people find it easiest to let oats sit in the fridge overnight (that’s where the name came from, after all!), and you can make the recipe up to five days in advance if you want. 

The Best Overnight Oat Recipes 

If you’re new to overnight oats, I recommend starting with my basic recipe and customizing your breakfast from there. There are so many ways to change the flavor of your oats with different mix-ins, so you’ll never get bored. I also like using these jars to make chia pudding! Here are several of my favorite recipes and topping ideas to get you started:

• Easy Overnight Oats
• Overnight Steel Cut Oats
• Easy Chia Pudding
• Chocolate Chia Pudding
