This post was first published in March 2018. I’ve since updated the recipe as well as some of the photos.

What’s your typical breakfast routine? I actually want to know. I sometimes wonder how in line with the rest of the world I am when it comes to breakfast – I feel like I know so many people that say they either don’t eat breakfast at all, or they have something like a piece of toast and coffee a couple of hours after waking up.

I want to know – HOW!? How do you get through the morning without something substantial in your stomach? Whoever came up with the term ‘hangry’ probably coined it after witnessing me one morning, an hour after waking up with nothing in my stomach yet. I’ve always woken up RAVENOUS! I have to eat the minute I get up, or at least snack on something while preparing breakfast if it’s something that takes a bit of time. The odd time I’ve gone a few hours without eating in the morning I find myself feeling weak and shaky, and extremely irritable. Please someone, tell me I’m not alone here….

Regardless of whether you turn into a complete crazy person or not, isn’t it nice to have something already prepared for breakfast upon waking up?! This is why I love breakfasts that you can prepare the night before, like my Nutella French toast bake, or these lemon overnight oats!

What are overnight oats?

Overnight oats are one of the easiest make-ahead breakfasts you can do, and there are unlimited possibilities!! It’s basically soaking large flake oats in some milk (non-dairy or dairy), along with some other flavors. It takes the guesswork (and the work) out of breakfast in the morning!

I’ve been trying out a few different overnight oats the past few months, but this one has been one of my favourites. I’m really into lemon these days, which I think has something to do with the fact that I’m dying for sunshine and summer and all of the bright and happy things. Did you see my Instagram stories from the weekend? I made homemade lemon curd for a lemon cake – sooo good! I’ll be posting that cake next week 🙂

Anyway, these overnight lemon poppy seed oats are super simple. Here’s what you do: get a bowl, measure out all of your ingredients, stir it all together. Done!

How much does this overnight oats recipe make?

My recipe makes enough for 1-2 breakfasts, depending on how much you like to eat in the morning! I usually double everything so there’s enough to feed all 4 of us, and sometimes there’s even a bit leftover. The beauty of overnight oats is you can make a huge batch to last you all week, since it keeps in the fridge for 3-4 days just fine.

These oats are terrific cold, making it a perfect grab-n-go breakfast, but I like to heat mine up a bit if I have the time. Use any type of milk you want.

Please let me know if you end up trying the oats, and whether they saved you from turning into a hangry monster like me 😉

  1. These overnight oats look and sound delicious! right up my alley with all the ingredients that you used….for beakfast I always have a greek yogurt with walnuts and blueberries, with an oj and green tea, breakfast is the most important meal of the day, I don´t know how some people either eat nothing or something unhealthy…great post and recipe 🙂

    1. Thank you Albert!! Breakfast is definitely the most important meal of the day – it gets everything started off on the right foot! Your Greek yogurt with walnuts and blueberries sounds like something I definitely need to try 🙂

  2. I get irritable when I’ve gone too long without eating so you aren’t alone. Weekday breakfasts for me usually involve something quick and then it’s a little more substantial on the weekend. I absolutely love lemon poppy seed anything and especially overnight oats so this is a total winner for me! Love that you topped this yumminess with blueberries too! Gotta give this a try!!!

    1. Haha I’m glad I’m not alone in that – I am scary when I’m hungry, especially first thing in the morning! I love lemon poppy seed too – you would love these oats!! Thanks Dawn! Hope you’re having a great week!

  3. My breakfast routine isn’t something that has been established – it’s changing. Normally, I need to eat something (like yogurt or oatmeal or even a spoon of peanut butter) especially if commuting is involved (I can easily get sick on an empty stomach). However, last year I had it differently as I would usually wake up early (before 5 a.m.) and walk to the gym (like 5 km) before my job, so most of those mornings I only had an apple/banana on my way with a normal breakfast few hours later. As you see, I’ve survived 🙂 But again, it’s not written in the stone, and I often wake up so ravenous that I cannot stop for the whole day haha. Oatmeal is one of my favorite breakfast meals, and I do like this version with poppy seeds. Delicious!

    1. Whaaat I don’t know how you walked 5km, and then worked out, and then went to work on nothing but an apple or banana. I’m shocked that you survived 😉 I think you need to start incorporating some overnight oats before these epic mornings of yours, Ben!

  4. I have always felt like there’s something wrong with me because I’m starving when I wake up. I can’t do brunch because there’s no way for me to wait that long to eat. . .and I come from a family of people who never eat breakfast so when I visit my parents I feel like a HUGE pig because I can’t shovel food into my mouth fast enough first thing in the morning. Phew. Thank you for letting me rant :). Overnight oats are one of my favorite things to eat in the morning so I’m definitely going to try these. LOVE all things lemon poppyseed!

    1. Hahah, I loved the rant. I can totally relate to you, Kelsie! My Mom often isn’t interested in breakfast first thing in the morning and when I go to visit, I’m devouring a huge bowl of cereal or whatever else I can get my hands on while she’s sipping her coffee….! I think we’re right, they’re wrong 🙂 You’ve got to try these oats my friend!!

  5. These pictures are just stunning! We sold lemon poppyseed muffins at my coffee shop and they were one of the most popular!
    I don’t typically eat my “breakfast “ or first meal until 1-2 pm. My body’s just used to it I think. I get up and go, go, go and sround 1pm is when I feel the hangry monster.

    1. Thank you so much, Patrick! I am not surprised about the popularity of the muffins at your coffee shop – they’re so good!! But wait – I can’t believe you don’t eat until after noon!!! That’s unreal to me. I would be a hot mess, haha!

  6. I have to eat first thing in the morning, so I’m right there with ya! YOU are not alone! 🙂 They look sooo delicious Katherine!! PInning for later dear!!

    1. Hooray! So glad I’m not alone in the hanger, Kim. Thanks for the pin!! Hope you’re having a great week 🙂

  7. You know I share your love of breakfast! I also wake up hungry in the morning, and need to eat before I do anything else. I love having overnight oats at the ready, and this lemon poppyseed version sounds perfect for spring!

    1. I’m so glad you’re with me on the breakfast train – overnight oats are the perfect solution for those mornings when you need to eat asap! Thanks Leanne!

  8. YUM!!! these look absolutely delicious 🙂 love the combo of poppyseed and lemon!

    1. Thank you my friend!! It is really the best combo!! Hope you’re having a great week!

  9. ahhh this sounds like such a tasty breakfast option! it depends on how i ate the night before- ie i had a massive cookie + ice cream way too late last night, so i wasn’t hungry enough for breakfast today. oops. but on a normal day, i’ll have oatmeal or yogurt + granola or toast or something.

    1. Hah – I can see that side of things too – eating way too much late at night will usually curb my appetite for breakfast too! Now you’re making me want cookies and ice cream! Thanks Heather 🙂

  10. Katherine, I know exactly what you mean, I also get so hungry in the morning and usually have at least a slice of toast with coffee to start the day. Now these lemon poppyseed overnight oats sound just so good, perfect and especially easy for weekday mornings. My son is a big fan of oats as well and I know that he will absolutely love this for his breakfast. Definitely pinning and saving to try 🙂
    Thank you for the great recipe 🙂

    1. I’m so glad you understand! I’m also glad you like the sounds of my oats 😉 We are all big oat eaters here, and everyone loved this one. I hope your son likes it!! Thanks for the pin my friend!
