Imagine pulling a golden, herb-flecked muffin from the fridge, warming it for thirty seconds, and sitting down to a deeply savory Italian breakfast that tastes like it took real effort — except all the work happened days ago. These batch-prep zucchini and walnut breakfast muffins are loaded with toasty walnuts, tender shreds of zucchini, and a fragrant blend of oregano, basil, and garlic that fills your kitchen with the aroma of an Italian bakery. Sun-dried tomatoes add pops of concentrated sweetness, while hemp hearts and nutritional yeast bring a rich, almost cheesy depth that makes these completely plant-based muffins taste indulgent.

Each two-muffin serving delivers roughly 40 grams of fat from coconut oil, walnuts, and hemp hearts, with only 6 grams of net carbs — a ratio that keeps you firmly in ketosis through your busiest mornings. At 12 grams of protein per serving from almond flour, hemp hearts, and flax, these muffins provide a solid foundation without any animal products. The generous fat content means they keep you satisfied for hours, avoiding the mid-morning energy crash that higher-carb breakfasts inevitably cause.

The real beauty of this recipe is its batch-prep design. One baking session yields twelve muffins — six servings that store beautifully in the refrigerator for up to five days or in the freezer for a full month. They reheat in under a minute, travel easily in a container for on-the-go mornings, and pair wonderfully with a cup of black coffee or a coconut cream latte. Whether you are a seasoned meal prepper or just looking for a way to simplify your keto mornings, this recipe earns its place in your weekly rotation.

Ingredients (serves 6)

Flax eggs:

  • 3 tablespoons (21g) ground flaxseed meal
  • 9 tablespoons (135ml) warm water

Muffin batter:

  • 1½ cups (144g) blanched almond flour
  • 2 tablespoons (20g) chia seeds
  • ⅓ cup (40g) hemp hearts
  • ¾ cup (90g) raw walnuts, roughly chopped
  • 3 tablespoons (15g) nutritional yeast
  • 1½ teaspoons dried oregano
  • 1 teaspoon dried basil
  • ½ teaspoon garlic powder
  • ½ teaspoon onion powder
  • ¾ teaspoon fine sea salt
  • ¼ teaspoon freshly ground black pepper
  • 1 teaspoon baking powder
  • ⅓ cup (73g) virgin coconut oil, melted and slightly cooled
  • 1 medium zucchini (about 200g), grated and squeezed dry
  • 2 tablespoons (14g) oil-packed sun-dried tomatoes, finely diced and patted dry
  • 1 tablespoon (15ml) fresh lemon juice

Optional topping:

  • 2 tablespoons (16g) raw hemp hearts
  • 1 tablespoon (6g) nutritional yeast
  • Flaky sea salt

Instructions

  1. Prepare the flax eggs. In a small bowl, whisk together the ground flaxseed meal and warm water. Set aside for at least 10 minutes until the mixture thickens to a gel-like consistency. This step is essential — flax eggs need time to develop their binding power.

  2. Preheat the oven and prepare the pan. Set your oven to 350°F (175°C). Line a standard 12-cup muffin tin with parchment liners or silicone liners, or grease the cups generously with coconut oil. Avoid paper liners without a light greasing, as the muffins can stick.

  3. Toast the walnuts. Spread the chopped walnuts on a small baking sheet and toast in the preheating oven for 5 to 6 minutes, until fragrant and lightly golden. Watch them carefully — nuts go from toasted to burnt quickly. Remove and set aside to cool.

  4. Mix the dry ingredients. In a large mixing bowl, whisk together the almond flour, chia seeds, hemp hearts, nutritional yeast, oregano, dried basil, garlic powder, onion powder, salt, black pepper, and baking powder. Make sure the baking powder is evenly distributed throughout.

  5. Squeeze the zucchini thoroughly. This is the most important step for the muffin texture. Place the grated zucchini in the center of a clean kitchen towel or several layers of cheesecloth. Twist and squeeze until no more liquid drips out. You should end up with about ¾ cup (roughly 130g) of squeezed zucchini. Excess moisture will make the muffins soggy and prevent them from holding together.

  6. Combine the wet ingredients. Add the thickened flax eggs, melted coconut oil, squeezed zucchini, diced sun-dried tomatoes, and lemon juice to the dry mixture. Stir with a spatula until everything is evenly combined. Fold in the toasted walnuts. The batter will be thick and slightly chunky — that is exactly right.

  7. Fill the muffin cups. Divide the batter evenly among the 12 muffin cups, filling each about three-quarters full. Use the back of a spoon to gently press and smooth the tops. If using the optional topping, sprinkle each muffin with a pinch of hemp hearts, a dusting of nutritional yeast, and a few flakes of sea salt.

  8. Bake until golden and set. Bake for 22 to 28 minutes, until the tops are golden brown and a toothpick inserted into the center comes out clean or with just a few moist crumbs. The edges should be slightly pulling away from the liner. The muffins will feel soft when warm but firm up significantly as they cool.

  9. Cool completely before storing. Let the muffins rest in the tin for 10 minutes, then transfer to a wire rack to cool completely. This cooling step is critical for meal prep — storing warm muffins creates condensation that leads to soggy, short-lived leftovers.

  10. Store for the week. Once fully cooled, place the muffins in an airtight container with a small piece of parchment between layers. Refrigerate for up to 5 days. To reheat, microwave one or two muffins for 25 to 35 seconds, or warm them in a 300°F (150°C) oven for 5 to 7 minutes until heated through.

Tips & Variations

Squeeze every drop from the zucchini. This cannot be overstated — watery zucchini is the number one reason these muffins turn out soft and crumbly instead of sturdy and sliceable. After grating, let the zucchini sit in a colander with a pinch of salt for five minutes to draw out extra moisture before wrapping and squeezing. You want the zucchini to feel almost dry to the touch.

Swap the walnuts for pecans or macadamia nuts. Pecans offer a buttery sweetness that pairs beautifully with the Italian herbs, while macadamia nuts add an ultra-rich, creamy bite and even more fat per serving. Avoid cashews — they are significantly higher in net carbs (about 8g per ounce compared to 2g for walnuts) and can push you out of ketosis.

Add a savory "parmesan" crust. For extra flavor and crunch, blend 3 tablespoons of hemp hearts with 2 tablespoons of nutritional yeast, a pinch of garlic powder, and a tiny pinch of salt in a spice grinder. Press this mixture onto the muffin tops before baking. It creates a golden, umami-rich crust that mimics parmesan beautifully without any dairy.

Watch hidden carbs in sun-dried tomatoes. Oil-packed sun-dried tomatoes are lower in sugar than the dry-packed variety, which are often treated with sulfites and concentrated sugars. Always check your label — some brands add sugar. At only 2 tablespoons across the entire batch, the carb contribution is minimal, but using a sugar-free brand keeps you on the safe side.

Freeze for longer storage. These muffins freeze exceptionally well for up to one month. Wrap each muffin individually in parchment paper, then place them all in a freezer-safe zip-top bag with the air pressed out. Thaw overnight in the refrigerator or microwave from frozen for 50 to 60 seconds. The texture holds up remarkably well through freezing and reheating.

Frequently Asked Questions

How do these muffins keep me in ketosis with almond flour and zucchini?
Almond flour is one of the most keto-friendly flours available, containing only about 3 grams of net carbs per quarter cup. The zucchini adds volume and moisture with almost no carb impact — a full medium zucchini has roughly 4 grams of net carbs, and that amount is spread across twelve muffins. Combined with the high fat content from coconut oil, walnuts, and hemp hearts, each two-muffin serving sits at approximately 6 grams of net carbs. That leaves plenty of room in a standard 20-gram daily net carb budget for the rest of your meals.
Can I use a different binding agent instead of flax eggs?
Chia eggs work as a direct substitute — use the same ratio of 1 tablespoon chia seeds to 3 tablespoons water per egg, and let them gel for 10 to 15 minutes. The texture will be very similar, though chia eggs can make the muffins slightly more dense. You could also use a commercial vegan egg replacer following the package directions for 3 eggs. Avoid aquafaba (chickpea liquid) here, as it does not provide the fat-binding strength needed and can add unwanted carbs from residual starch.
How should I store and reheat these for the best texture?
For refrigerator storage, keep the muffins in an airtight container lined with a paper towel to absorb any condensation. They stay fresh and flavorful for a full five days. The microwave is the fastest reheating method — 25 to 35 seconds brings them back to warm and tender. For a crispier exterior, reheat in a toaster oven or conventional oven at 300°F (150°C) for 5 to 7 minutes. Avoid reheating in a covered container, as trapped steam makes the tops soft and damp.
I follow standard vegetarian keto with dairy and eggs — how can I adapt this?
If you eat eggs, replace the three flax eggs with three large beaten eggs for an even sturdier, more protein-rich muffin — this will add roughly 6 grams of protein per serving and improve the rise. For dairy, you can swap the coconut oil for melted butter and add 2 to 3 tablespoons of grated Parmigiano-Reggiano to the batter for authentic Italian flavor. A tablespoon of cream cheese per muffin cup, dropped into the center before baking, creates a delicious creamy surprise in the middle.
My muffins fell apart when I tried to remove them from the pan — what went wrong?
The two most common causes are excess moisture from the zucchini and insufficient cooling time. Make sure you squeeze the grated zucchini until it is nearly dry — you should be able to extract at least 3 to 4 tablespoons of liquid from one medium zucchini. Second, these muffins must cool in the pan for a full 10 minutes before you attempt to remove them. The coconut oil needs time to set as it cools, which is what gives the muffins their structural integrity. If they still feel fragile, let them cool an additional 5 minutes on the wire rack before handling. Using parchment or silicone liners also makes removal much easier.
