Best Spices for Oatmeal

Plain oatmeal is mild, so a little spice changes it a lot. Cinnamon is the go-to, followed by vanilla, nutmeg and ginger, and a University of Delaware extension recipe uses three of them in one bowl. A ready-made blend does several at once; McCormick even names oatmeal as a use for its apple pie spice. Just read the label, since pumpkin pie spice from one brand can skip the cloves entirely. And if you eat heavily cinnamoned oats every morning, the coumarin note below is worth a minute.

Why oatmeal takes spice well

Rolled oats are one of the whole-oat sources the FDA allows to carry a labeled heart-health claim, as long as a serving has at least 0.75 g of their soluble fiber.⁸ That claim is about the oat fiber, not the spices. Spice is about flavor, and a little cinnamon or vanilla does more for a bowl of oats than extra sugar.

One recipe, three spices

The University of Delaware Cooperative Extension’s Carrot Cake Oatmeal shows how the usual spices work together. It cooks a single serving of rolled oats in almond milk with grated carrot and seasons it with cinnamon as the lead spice, a much smaller amount of ground ginger and some vanilla extract. Maple syrup and a pinch of salt finish it.¹ The recipe is generous with cinnamon, which suits the carrot.

For a bowl of plain oatmeal (about ½ cup dry oats), start with ½ teaspoon ground cinnamon, ½ teaspoon vanilla extract and a pinch of ground ginger or nutmeg. Taste and go from there.

The core spices

Cinnamon: the default

Two kinds of bark get sold as cinnamon: Ceylon or “true” cinnamon, and cassia. Cassia is the type you’ll most often find in North America. The Netherlands Enterprise Agency’s CBI market study describes Ceylon as milder and finer.⁹ Cassia gives you a bold, candy-like cinnamon; Ceylon is gentler. See Ceylon vs. cassia cinnamon, Saigon cinnamon and cinnamon vs. nutmeg.

Cinnamon can go in while the oats cook or on top at the end. Stir it in early and it spreads evenly; dust it on top and you get a stronger first hit of aroma.

A note on coumarin. Cassia contains coumarin. Germany’s Federal Institute for Risk Assessment (BfR) calculates that a 60 kg adult reaches the tolerable daily intake by eating about 2 g of cassia with average coumarin content a day.¹⁰ If you eat heavily cinnamoned oatmeal every morning, measure it, or switch to Ceylon cinnamon. NIH’s National Center for Complementary and Integrative Health (NCCIH) sums up that research doesn’t clearly support cinnamon for any health condition.¹¹ See too much cinnamon.

Vanilla: the background note

The extension recipe adds vanilla extract next to its cinnamon.¹ In the US, anything labeled vanilla extract has to contain at least 35% ethyl alcohol by volume.¹² Seeds scraped from a pod give you visible specks and a fuller flavor; extract is easier to measure. See vanilla extract substitutes, vanilla sugar and too much vanilla.

Nutmeg: a little goes a long way

A small grating of nutmeg stirred in near the end is plenty for a bowl. Kitchen amounts aren’t a safety concern: the National Capital Poison Center says none of the foods and flavorings it discusses, nutmeg included, is dangerous when used as recommended.¹³ See fresh vs. ground nutmeg, cooking with nutmeg and too much nutmeg.

Ginger: sharper warmth

The extension recipe pairs a small amount of ground ginger with its cinnamon.¹ Ground ginger stirs into hot oatmeal easily. Fresh grated ginger is brighter and sharper. See fresh ginger vs. ground ginger.

Spice blends

Blends get you several warm spices at once, but none of them has a fixed recipe. Read the label.

Blend	What named sources put in it
McCormick Apple Pie Spice	Cinnamon, nutmeg and allspice; McCormick names oatmeal among its uses²
McCormick Pumpkin Pie Spice	Cinnamon, ginger, nutmeg, allspice and sulfiting agents; no cloves³
Food Hero Pumpkin Pie Spice (Oregon State)	Cinnamon-led, with ginger and smaller amounts of nutmeg and cloves⁴
Masala chai spices: Saveur, Dishoom, Culinary Institute of America	All three use green cardamom, cinnamon, ginger and cloves; two add black pepper and two fennel seed⁵⁶⁷

Pumpkin pie spice leads with cinnamon, not cloves. McCormick’s version has no cloves at all, and the Oregon State recipe uses four times as much cinnamon as cloves.³⁴ For chai, the CIA notes that chai masala mixes may include cardamom, cinnamon, ginger and peppercorns.⁷ In oatmeal, a quarter to half teaspoon of any blend per bowl is a fine start.
