How to Make Oat Milk with Tasty Warming Herbs

As the nights get longer and days get colder, you can find me curled up on the couch with a good book and a cup of homemade herbal oat milk…

With its subtle, sweet taste and nourishing properties, homemade oat milk has quickly become my drink of choice during the cold months of fall and winter.

Why go to the trouble of making oat milk, when you can easily buy it at the grocery store?

Well, here’s the thing: homemade oat milk tastes way better than store bought oat milk, and it’s a whole lot cheaper. Not to mention, it’s incredibly easy to make — to make plain oat milk, all you need is water, rolled oats, a blender, a strainer, and a few minutes of your time.

And, if you want to geek out on herbs (which if you’re on this page I think it’s safe to assume you’re probably an herb nerd like me!), you can customize your oat milk by flavoring it with different blends of herbs.

In the summers I add cooling herbs like linden and lemon balm to my oat milk to help me stay calm and cool throughout the long, sunny days. And during the colder months, I add pungent herbs like ginger, rosemary, and cinnamon to increase circulation and help me stay warm.

In today’s recipe, I’ll show you how to make a warming oat milk with rosemary, ginger, cinnamon, and cardamom. But before we dive into this simple recipe, let’s take a look at some of the benefits of oats and these warming herbs…

Oats (Avena sativa)

Home herbalists have long used oatmeal as a strength-giving cereal. With their subtle flavor and rich mineral content, oats can gently nourish the body as a daily breakfast or as a post-illness protocol. The slimy texture of oatmeal porridge also gives us a hint about its other properties: this sliminess is what herbalists often refer to as “demulcency.” A demulcent herb or food can cool, moisten, and soothe inflamed tissues. Oatmeal particularly shines at soothing inflamed tissues in the digestive tract and topically on the skin. Though I usually drink my oat milk, every now and then I also like to apply plain oat milk topically as a facial cleanser to nourish and soothe my skin.

Rosemary (Salvia rosmarinus)

Rosemary is a warming culinary herb that can increase circulation throughout the body and tonify the cardiovascular system as a whole. It can also gently uplift mood and help ease stagnant digestion, including gas or bloating. I like to nibble on fresh rosemary leaves when I feel the winter blues, and the effects are almost immediate: the first bite of rosemary quickly warms my body, and I can feel my mood start to subtly shift and soften.

This combination of warming and uplifting properties makes rosemary a perfect addition to this herbal oat milk for the colder months.

boost your immune system with ginger

Ginger (Zingiber officinale)

Honestly, what can’t ginger do? This pungent herb can ease inflammation, support immune function, increase circulation, promote healthy digestion, and address menstrual cramps. And this is just the tip of the iceberg! If you want to get to know one culinary herb, ginger is a great place to start.

types of cinnamon

Cinnamon (Cinnamomum verum)

Cinnamon offers a tasty combination of sweetness and spice that can satiate sugar cravings and increase circulation. As a warming aromatic herb, it can also address sluggish digestion. During the colder months when people tend to eat heartier foods, cinnamon is an herbal ally that can support healthy, easeful digestion.

Cardamom (Elettaria cardamomum)

Much like cinnamon, this warming aromatic herb can address sluggish digestion and cramping.  And cardamom’s striking flavor adds a harmonizing note to the blend of herbs in this creamy oat milk.

Spiced Oat Milk

Delightfully warming and easy to make, this spiced oat milk recipe is perfect for a cold fall or winter day. Herbal oat milk pairs nicely with a good book, warm socks, and a cozy blanket. Enjoy!

What you’ll need…

  • 1 cup rolled oats
  • 3.5 cups of water
  • 1 tablespoon fresh chopped rosemary leaves (or 1 teaspoon dried rosemary leaves)
  • ½ teaspoon Ceylon cinnamon powder
  • 1 tablespoon freshly grated ginger
  • 1/4 teaspoon cardamom powder
  • A pinch of sea salt
  • Honey to taste (optional)
  1. Add the rosemary, cinnamon, cardamom, and ginger to a large jar. Bring the water to a boil and pour it over the herbs in the jar. Cover the jar with a lid and let steep for 15 minutes.
  2. Strain out the herbs and let the tea cool on the counter. Once it has cooled to room temperature, put the tea in the fridge to cool down further. Then once it is chilled (that is, roughly the temperature in your fridge), you can proceed to the next step.
  3. Once the tea has finished cooling, add it and the rolled oats to a blender. Blend for 30 seconds. Check to see if the oats have been thoroughly blended into smaller pieces. If not, blend for another 15–30 seconds.
  4. Strain the mixture through 2 fine mesh strainers to ensure that your oat milk is not too thick.
  5. Add a pinch of sea salt to your oat milk, and if desired, honey to taste.
  6. Refrigerate your oat milk. In the fridge, this oat milk will keep for up to 3 days. Separation will naturally occur in your oat milk, with heavier oat particles sinking to the bottom of the jar. To address this separation, you can simply shake your oat milk before consuming it.

Note: After you’ve finished making your oat milk, I recommend not heating it up. Heating the oat milk will make the milk thicker and slimy. Luckily, the warming herbs in this milk will add a nice kick of heat to the milk so you don’t have to heat it to still experience the warming benefits of this oat milk recipe.

Yield: several servings! You can drink this herbal oat milk by the mugful or add it to your morning coffee, cereal, and more.
