Keto Bread: The Complete Guide to Recipes, Brands & Flours
Keto bread is bread made with a low-carb flour — usually almond, coconut, or lupin flour — instead of wheat, plus a binder like psyllium husk or xanthan gum to hold the crumb together without gluten. A slice typically runs about 0 to 4 g net carbs, compared with roughly 10 to 13 g in a slice of regular bread, so it fits comfortably inside a standard 20 to 50 g daily net-carb budget. This guide covers the carb math, the flours and binders that make it work, our two homemade recipes, and how store-bought brands compare.
A note on who this isn't for: most keto bread recipes, including ours, are built on almond flour — a tree nut. If you or anyone you're serving has a tree-nut allergy, skip the almond-flour recipes and use a coconut-flour or store-bought nut-free option instead. And as with any significant diet change, talk to your healthcare provider before adopting a low-carb pattern long-term, especially if you're pregnant, manage diabetes with insulin, or have kidney or liver disease.
Bread is one of the first things people miss on keto, and it's also one of the easiest to replace well. Whether you'd rather bake a loaf, microwave a single mug slice in 90 seconds, or just buy a bag off the shelf, the options below all land in roughly the same net-carb range — the difference is time, texture, and price.
Is bread keto? How many net carbs does it have?
Regular bread isn't keto — a single slice of white sandwich bread runs about 13 g total carbs with less than 1 g of fiber, so nearly all of it counts as net carbs.1 Two slices for a sandwich can eat up half of a strict 20 g daily budget before you've added anything else. Keto bread solves this by replacing most or all of the wheat flour, which is where the carbs come from in the first place.
| Bread | Net carbs per slice/serving | Notes |
|---|---|---|
| White sandwich bread | ~13 g | Almost entirely starch; under 1 g fiber |
| Whole wheat bread | ~10 g | Slightly more fiber than white, still high net carbs |
| Store-bought keto bread (average) | 0–4 g | Varies by brand — see comparison below |
| Homemade almond flour loaf | ~1–2 g | Depends on slice thickness and exact recipe |
| Homemade 90-second mug bread | ~2–3 g | Per single-serving mug; lower with coconut flour |

What makes bread "keto"?
Keto bread replaces wheat flour with a low-carb flour and adds a binder to replace the structure gluten normally provides, plus extra egg for lift. Wheat flour is almost entirely starch, which is why it drives up net carbs so fast; low-carb flours swap most of that starch for fiber, fat, or protein instead.
- Low-carb flour base. Almond flour, coconut flour, and lupin flour are the three most common. Almond flour runs about 10–11 g net carbs per 100 g (roughly 21 g total carbs minus about 11 g fiber); coconut flour is even more fiber-dense, at roughly 21–24 g net carbs per 100 g, though recipes use far less of it by weight because it absorbs so much liquid.1 Lupin flour, a legume-based flour, is reported by some brands at as little as 2–5 g net carbs per 100 g thanks to an unusually high fiber and protein content, though figures vary more by brand than almond or coconut flour do.
- Binders. Wheat flour's gluten is what normally traps air and holds a loaf together. Without it, recipes lean on psyllium husk powder (almost pure fiber, contributing negligible net carbs) or xanthan gum (used in tiny amounts, also negligible) to mimic that stretch and chew.
- Eggs and egg whites. Low-carb flours don't rise the way wheat does, so most keto bread recipes use more eggs than a traditional loaf — they add structure, lift, and moisture that flour alone can't provide.

What are the best keto bread recipes?
Both of our recipes below use almond flour as the base and include a nut-free swap. Each has a full ingredient list, step-by-step method, and nutrition breakdown.
- Almond Flour Keto Bread — the standard oven-baked loaf: sliceable, freezer-friendly, and the closest texture to real sandwich bread.
- 90-Second Keto Bread — a single-serving mug bread ready in under five minutes, with an almond-flour and a coconut-flour version.
Both recipes use the same core technique — a low-carb flour, egg for structure, and baking powder for lift, finished with direct heat (baking or toasting) to build a real crust — rather than relying on a microwave alone, which cooks the crumb through but never browns the surface.
What are the best store-bought keto bread brands?
If you'd rather not bake, brands like Sola, Base Culture, Franz Keto, ThinSlim Foods, and Aldi's L'Oven Fresh Keto line currently list 0 to 4 g net carbs per slice on their labels. None of them lean on sugar alcohols to hit that number — most swap in wheat protein isolate, vital wheat gluten, or nut flour instead of, or alongside, wheat starch.

How should you choose a keto flour?
Almond flour is the best all-around choice for most keto bread — it has a mild flavor and behaves closest to wheat flour by volume — while coconut flour and lupin flour work best in small amounts or in specific recipes built around them. Reach for coconut flour when you want a lighter texture and don't mind adding extra liquid and eggs to compensate for how much moisture it absorbs; reach for lupin flour if you're avoiding tree nuts and want a higher-protein, higher-fiber option, though it's harder to find and pricier than almond or coconut flour.
Our keto flours explained guide ranks every common option by net carbs per 100 g, best uses, and 1:1 substitution notes, including binders like psyllium husk and flours to avoid (rice flour, "low-carb" blends with hidden starches).
How does keto bread fit into your daily carb budget?
Even the higher end of keto bread — about 4 g net carbs per slice — leaves most of a standard 20 to 50 g daily net-carb budget for the rest of your meals. Two slices of a mid-range store-bought brand cost about 6–8 g net carbs total; a full homemade almond-flour sandwich costs closer to 2–4 g.
To set your own number and see exactly where bread fits:
- Review the assumptions behind a daily carbohydrate amount in our guide to calculating your keto macros. For packaged bread, the net-carb estimate calculator can apply explicit deductions to the values on one label; it does not set the daily amount.
- Check any specific bread — homemade or store-bought — against your remaining budget with the net-carb calculator.
- Build the rest of your day's meals around the keto food list so bread stays a small, planned part of your total, not a guess.
