Easy Low Carb Nut Free Keto Irish Soda Bread Recipe

This Low Carb Keto Irish soda bread is amazing in texture and is nut free, low carb, grain free and a gluten free bread recipe! Just 5 grams of net carbs per serving!

Grain Free Irish Soda Bread (Low Carb, Sugar Free, Nut Free Option)

This Grain Free Irish Soda Bread is a delicious low-carb twist on the traditional Irish quick bread that’s often served around St. Patrick’s Day.

My version is keto friendly, gluten free, sugar free, and grain free, yet still delivers the rustic texture and slightly tangy flavor that makes classic soda bread so comforting.

When I first published this recipe back in 2015, sunflower seed flour wasn’t easy to find in grocery stores. So I created a nut-free Irish soda bread by grinding raw sunflower seeds in my food processor to make homemade sunflower seed flour.

Today, thankfully, sunflower seed flour is widely available, which makes this recipe much easier to prepare. No grinding required!

Simply use sunflower seed flour for a completely nut-free low-carb soda bread, or substitute almond flour if you don’t have nut allergies.

This updated method saves time while keeping the same hearty, satisfying results.

What Is Traditional Irish Soda Bread?

Traditional Irish soda bread is a simple quick bread made without yeast. Instead, it rises thanks to the reaction between baking soda and buttermilk, which creates bubbles that help the bread rise.  

Historically, soda bread became popular in Ireland during the 1800s because it was inexpensive and easy to make, requiring only a few basic ingredients.  

The most traditional recipes contained just four ingredients:

• Flour
• Baking soda
• Salt
• Buttermilk  

Modern versions—especially in the United States—often include additions like butter, eggs, sugar, or raisins.

My recipe keeps the rustic texture and flavor of soda bread, while making it grain free and low carb so it fits a keto lifestyle.

Why You’ll Love This Low Carb Irish Soda Bread

If you’re following a low carb, keto, or sugar-free lifestyle, traditional soda bread made with wheat flour simply doesn’t fit your macros.

This recipe solves that problem.

It’s:

✔ Grain free

✔ Sugar free

✔ Keto friendly

✔ Low carb

✔ Nut free option

✔ St. Patrick’s Day perfect

And it still delivers the rustic, hearty loaf texture that Irish soda bread is known for.

It’s also a wonderful bread to serve alongside:

Carbs in Traditional Irish Soda Bread

Traditional Irish soda bread is made with all purpose flour, buttermilk, salt and baking soda.

According to Cronometer, 1 slice, or about 60 grams has 165 calories, and 31.7 grams total carbs. Too high for a ketogenic diet and would kick you out of ketosis. 

Our low carb keto-friendly recipe for Irish soda bread has 7 grams total carbs per serving. Much better for a keto diet or low carb diet and would not kick you out of ketosis. 

Nut Free Irish Soda Bread

Here’s the thing about making a nut free, grain free Keto Irish soda bread: It will not be identical to traditional, but it will still be a delicious bread for your St. Patrick’s day celebrations. If you can get passed the fact it will be different in texture, you will love this recipe.

But the big deal about having a child with tree nut allergies is, I can’t use low carb flours like almond flour.

Nut-Free vs Almond Flour Options

One of the most common questions I get from readers is:

Can I make this bread with almond flour instead of sunflower seed flour?

Yes!

This recipe works beautifully either way.

Nut-Free Version

Use sunflower seed flour for a completely nut-free loaf.

This is perfect for:

• nut allergies
• school safe baking
• those avoiding almond flour

Sunflower seed flour gives the bread a hearty texture similar to whole-grain breads.

Almond Flour Version

If you don’t need a nut-free option, you can substitute fine blanched almond flour.

Almond flour creates a slightly softer crumb and lighter color.

Both versions are low carb and keto friendly.

Tools needed Low Carb Irish Soda Bread

Cast iron skillet– The one I used is 8 inches. It makes for a perfect round loaf.

You can use this cast iron skillet for a bunch of other keto recipes like my Deep Dish Cauliflower Pizza and my Keto Chocolate Chip Skillet Cookie Pie. 

Food Processor– This works wonderfully to chop nuts and seeds finely, making this nut free keto bread perfect in texture with a crusty exterior, with little effort on your part. 

Why I Love Sunflower Seed Flour

Sunflower seed flour has become one of my favorite nut-free low carb baking flours.

Benefits include:

• naturally grain free
• nut free
• gluten free
• mild flavor
• high in healthy fats
• good source of vitamin E and magnesium

It’s also a great option for people who enjoy keto baking but want a break from almond flour.

If you’ve ever ground sunflower seeds in a food processor before, you’ll appreciate how much easier this recipe is now that sunflower seed flour is readily available.

Tips for Perfect Soda Bread Texture

Soda bread is very different from yeast bread.

Because it relies on baking soda instead of yeast, the dough should be handled very gently.

Traditional soda bread dough is typically mixed quickly and shaped into a round loaf without kneading.  

Some tips for success:

• Don’t overmix the dough

• Shape into a rustic round loaf

• Score the top before baking

• Bake immediately after mixing

The classic cross cut on top of soda bread is both decorative and practical—it allows heat to penetrate the loaf during baking.

Perfect for St. Paddy’s Day
