Creamy Avocado Breakfast Muffins with Eggs and Spinach
There is something deeply satisfying about pulling a warm tray of egg muffins from the oven on a busy morning. These creamy avocado breakfast muffins with eggs and spinach hit every note you want from a morning meal: rich, savoury flavour, a silky avocado filling that melts into each bite, and a protein hit that keeps you full well past lunchtime. Each muffin clocks in at around 140 calories with 10 grams of protein, making this one of those rare recipes where eating well feels genuinely indulgent rather than like a compromise.
The secret to the creaminess here is mashing ripe avocado directly into the egg mixture before baking, rather than serving it on the side as an afterthought. When avocado bakes gently inside the muffin cups, it softens into a velvety, almost custard-like texture that binds everything together beautifully. Baby spinach wilts down to almost nothing during cooking, but it quietly does its job, adding folate, iron and fibre without overwhelming the flavour. A small amount of crumbled feta gives a salty tang that lifts the whole thing without piling on excess calories. You really do not need much at all.
This recipe was designed specifically to outperform traditional egg muffin recipes on the nutrition front. Most versions rely on heavy cream or full-fat cheese in generous quantities, which sends the calorie count soaring. Here, the avocado provides all the richness you need from its natural healthy monounsaturated fats, so you can keep the dairy light and still get that luxurious mouthfeel. The oat flour base used in the outer shell adds a gentle fibre boost and a slightly nutty flavour that pairs brilliantly with the green vegetables. For anyone watching carbohydrates, these still sit comfortably low on the glycaemic scale, and they are naturally gluten-free when you use certified gluten-free oat flour.
Meal prep is where these muffins truly shine. Bake a full tray of twelve on Sunday afternoon and you have breakfast sorted for the entire working week. They reheat in about 60 seconds in the microwave, or you can eat them cold straight from the fridge, which honestly works just as well once you get used to it. Store them in an airtight container and they stay fresh and firm for up to four days. Busy mornings, early gym sessions, rushed school runs: these little muffins handle all of it without you having to think twice about what you are eating.
Ingredients
- 2 large ripe avocados (flesh only, mashed smooth)
- 8 large eggs (free-range if possible)
- 90 g baby spinach (roughly chopped)
- 60 g crumbled feta cheese (reduced-fat variety works well)
- 4 tablespoons certified gluten-free oat flour (for structure and fibre)
- 3 tablespoons plain low-fat Greek yogurt (adds creaminess and protein)
- 1 tablespoon fresh lemon juice (prevents avocado browning and brightens flavour)
- 1 teaspoon garlic powder
- 0.5 teaspoon onion powder
- 0.5 teaspoon smoked paprika (adds gentle warmth)
- 0.3 teaspoon fine sea salt (adjust to taste)
- 0.3 teaspoon black pepper (freshly ground)
- 80 g cherry tomatoes (halved, for topping)
- 1 tablespoon extra virgin olive oil (for greasing the muffin tin)
- 2 tablespoons fresh chives (finely chopped, for garnish)
Instructions
- 1
Preheat your oven to 190 degrees Celsius (375 degrees Fahrenheit). Brush a 12-cup standard muffin tin generously with olive oil, making sure to coat the sides and base of each cup thoroughly. Set aside.
Silicone muffin trays work brilliantly here and need very little greasing. They also make it easier to pop the muffins out cleanly once baked.

Halve the avocados, remove the stones and scoop the flesh into a large mixing bowl. Add the lemon juice immediately and mash with a fork until very smooth with no large lumps remaining. The texture should resemble a thick, creamy paste.
The lemon juice does double duty: it stops the avocado from oxidising to brown during baking and adds a subtle brightness that cuts through the richness.
- 3
Crack all 8 eggs into the bowl with the mashed avocado. Add the Greek yogurt, garlic powder, onion powder, smoked paprika, salt and black pepper. Whisk everything together firmly until fully combined and the mixture looks uniform in colour and texture.
Do not over-whisk. You want the eggs incorporated but not overly aerated, which keeps the muffins dense and satisfying rather than spongy.
- 4
Fold in the oat flour using a spatula, stirring gently until no dry pockets remain. Then fold in the chopped baby spinach and crumbled feta cheese. The spinach will look like a lot at first but it will wilt and shrink significantly during baking.
For even more flavour, lightly saute the spinach in a dry pan for 90 seconds before adding it to the mixture. This removes excess moisture and concentrates the taste.
- 5
Divide the mixture evenly among the 12 prepared muffin cups, filling each one to about three-quarters full. Place two cherry tomato halves on top of each muffin, pressing them in very gently so they sit just on the surface.
A large cookie scoop or ladle makes portioning much faster and keeps each muffin a consistent size, which means they all bake evenly at the same rate.
- 6
Transfer the tin to the preheated oven and bake for 20 to 22 minutes, until the muffins are set in the centre and lightly golden around the edges. A toothpick inserted into the middle of a muffin should come out clean with no wet batter clinging to it.
Start checking at the 18-minute mark as oven temperatures vary. You want the centres just set, not rubbery. Slightly underbaked is better than overdone with egg muffins.
- 7
Remove the tin from the oven and allow the muffins to cool in the tin for 5 minutes. This resting time helps them firm up and makes them much easier to remove without breaking. Run a thin knife around the edge of each muffin cup before lifting them out.
- 8
Scatter the fresh chopped chives over the top of each muffin just before serving. Enjoy them warm immediately, or allow them to cool completely before transferring to an airtight container for storage.
A small dollop of extra Greek yogurt or a light drizzle of hot sauce on top when serving takes these from great to genuinely restaurant-quality.

Pro Tips
- ✓
Use very ripe avocados for the creamiest texture. The flesh should yield easily when pressed and have no firm or stringy patches.
- ✓
Do not skip the lemon juice. It is essential for both flavour and preventing the green colour from turning dull during baking.
- ✓
Muffins continue to firm up as they cool, so do not judge the set by the jiggle test straight out of the oven.
- ✓
If your muffin tin is older and prone to sticking, line the cups with parchment paper squares instead of relying on oil alone.
- ✓
For extra protein, stir in two tablespoons of unflavoured collagen peptides or additional crumbled feta before baking.
- ✓
Chop the spinach finely rather than leaving large leaves. Smaller pieces distribute more evenly through each muffin.
- ✓
These taste excellent cold, straight from the fridge. You genuinely do not need to reheat them if you are eating on the go.
Frequently Asked Questions
Variations
- •
Dairy-Free Version
Replace the Greek yogurt with unsweetened coconut yogurt and swap the feta for a dairy-free crumbled cheese or simply leave it out. The avocado provides enough creaminess on its own.
- •
Extra Protein Boost
Stir in 60 grams of finely diced cooked turkey breast or flaked canned tuna into the mixture before portioning into the muffin tin. This pushes the protein per muffin well above 14 grams.
- •
Spicy Chipotle Kick
Add half a teaspoon of chipotle powder and a quarter teaspoon of cayenne pepper to the egg mixture for a smoky, fiery version that pairs beautifully with a dollop of plain yogurt on top.
- •
Mediterranean Style
Swap the cherry tomatoes for sun-dried tomatoes and add a handful of pitted Kalamata olives and a teaspoon of dried oregano. This variation has a bolder, more intensely savoury flavour profile.
Substitutions
- •Feta cheese → Goat cheese or nutritional yeast (Goat cheese gives a similar tang with a creamier texture. Nutritional yeast (2 tablespoons) works well for a completely dairy-free version and adds a pleasant cheesy flavour.)
- •Baby spinach → Kale or Swiss chard (Remove tough stems and chop very finely. Kale and chard are slightly more robust than spinach so they hold their texture a little more during baking, which some people prefer.)
- •Oat flour → Almond flour or coconut flour (Use the same quantity of almond flour for a seamless swap. If using coconut flour, reduce to just one tablespoon as it is far more absorbent and will make the muffins too dense otherwise.)
- •Greek yogurt → Cottage cheese (blended smooth) (Blended low-fat cottage cheese works as a direct swap and actually increases the protein content slightly. Blend it first to remove any lumps before adding to the mixture.)
- •Cherry tomatoes → Roasted red peppers or sun-dried tomatoes (Both options add a lovely sweetness and colour to the tops of the muffins. Slice them into small pieces first so they sit neatly on the surface without sliding off during baking.)
🧊 Storage
Store cooled muffins in an airtight container in the refrigerator for up to 4 days. Reheat individually in the microwave for 50 to 60 seconds, or in an oven preheated to 160 degrees Celsius for 8 minutes. Not recommended for freezing due to the avocado content.
📅 Make Ahead
These muffins are ideal for Sunday batch cooking. Prepare and bake the full tray, cool completely and refrigerate in a sealed container. Grab one or two each morning throughout the week. The flavours actually deepen overnight, making day two taste even better than day one.
