Discover why Kernza—a perennial grain developed by The Land Institute—is more sustainable than wheat, saves growers time and money, and adds rich, nutty flavor to breads and waffles. Learn how we use Kernza in our baking.
Kernza is one of the most interesting ingredients to reach the baking world in decades— it is a breakthrough for farmers and the future of sustainable agriculture. Developed by The Land Institute in Kansas, Kernza is a perennial grain derived from intermediate wheatgrass. Unlike traditional wheat, which must be re-planted every year, Kernza grows back season after season from the same root system. That single difference results in huge environmental advantages, reduced costs for growers, and a deliciously nutty new flour for bakers.
Below, we’ll share why Kernza is more sustainable than wheat, how it saves farmers money and labor, and how we’ve been using it in our baking—especially bread and waffles, where its warm, nutty flavor really shines.

Why Kernza Is More Sustainable Than Wheat
1. Kernza Has Deep, Permanent Roots
One of the biggest advantages of Kernza is its root system.
While wheat roots typically reach 1–3 feet, Kernza’s roots can grow 10 feet or deeper.
These deep roots allow the plant to:
- Pull water from deeper soil layers
- Capture nutrients more efficiently
- Keep soil intact year-round
- Build long-term soil carbon
Deep roots = healthier soil and more resilient crops.
2. It Reduces Soil Erosion
Because Kernza stays in the ground year after year, the soil is never left bare or freshly tilled. This prevents erosion—one of the biggest long-term threats in wheat-growing regions. Continuous living roots help stabilize the soil and protect it from wind and water loss.
3. It Requires Less Irrigation
Kernza is naturally drought-tolerant. Those deep roots reach moisture that annual wheat cannot access, meaning farmers can use significantly less irrigation, an enormous benefit in water-stressed agricultural areas.
4. Kernza Requires Fewer Inputs
Since growers don’t need to replant Kernza every season, they reduce:
- Seed costs
- Fuel for machinery
- Labor hours
- Fertilizer needs
This makes Kernza not only more sustainable but also more cost-effective. Many growers report lower overall expenses with a more predictable, stable harvest system.
5. It Lasts for Years Without Replanting
Because Kernza is perennial, fields don’t need to be tilled and reseeded annually. This eliminates a major portion of a farmer’s workload while improving soil structure and biodiversity. Less tillage also means less carbon released into the air.
6. It Helps Build Soil Carbon
Perennials are known for drawing carbon from the atmosphere and storing it long-term in the soil. Kernza’s deep root system enhances this effect, making it a powerful tool in regenerative agriculture and climate-forward farming.
How We Use Kernza in Baking
The first thing you notice about Kernza flour is its warm, nutty, toasted flavor. It tastes like a cross between whole wheat, toasted barley, oats and a hint of graham. It’s flavorful enough to stand out but gentle enough to blend beautifully with other flours. However, it is a whole wheat, so we usually mix it with King Arthur Bread Flour or All Purpose Flour.
Kernza in Bread
Kernza’s mild sweetness and nutty flavor make it ideal for artisan loaves and enriched breads, like in our recipe for the best walnut bread. We often use it in:
- Our Master Holiday Bread Method (it adds depth without weighing down the dough)
- Sandwich loaves for a warm, wholesome flavor
- Rustic batards with a darker crust
- Rolls and buns with a subtle whole-grain character
We usually blend 20–40% Kernza flour with bread flour for the best structure and rise.
Kernza in Waffles
Waffles are one of the best places to experience Kernza’s flavor, so we have added it to our Best Yeast Waffle Recipe.
The grain adds:
- A naturally nutty aroma
- Beautiful golden color
- Crisp edges with a tender center
- A wholesome, slightly sweet base
Waffles complement Kernza’s flavor perfectly—especially when topped with maple syrup, honey, or small-batch preserves.
Kernza in Cookies, Muffins, Quick Breads and Crackers
Kernza works well in softer baked goods too:
- Chocolate chip cookies with a deeper, warmer flavor
- Banana bread with a richer base
- Blueberry muffins with a hint of graham cracker in every bite
- Easy Norwegian Crackers
Its flavor is more pronounced than wheat, so even small amounts make a difference.
Where Kernza Was Developed
Kernza was developed by The Land Institute, a nonprofit agricultural research organization in Salina, Kansas. Their goal is to create perennial versions of common food crops to make agriculture more sustainable, resilient, and environmentally sound.
Kernza is their most well-known achievement—one that continues to grow in popularity among bakers, chefs, and farmers worldwide.
Why Kernza Belongs in a Sustainable Kitchen
Kernza offers something rare: a grain that is better for the planet, better for growers, and genuinely delicious to bake with. Whether you use just a scoop in your weekly bread baking or make waffles with entirely Kernza flour, it’s an easy way to add richness, nutrition, and a strong sustainability story to your cooking.
True to The Master Pantry philosophy, this recipe combines the best seasonal ingredients and quality brands with homemade methods to maximize both flavor and sustainability. It was inspired by our travels and works well as a holiday recipe.
