With the arrival of spring, fresh, seasonal ingredients return to our plates—and asparagus is an absolute must. This versatile vegetable isn’t just a culinary highlight; it also offers a range of health benefits, especially for your gut microbiome.
The gut microbiome (also known as gut flora) refers to the entire community of microorganisms—mainly bacteria—living in your digestive tract. These tiny inhabitants play a crucial role in your overall health, often more than we realise. To function at their best, they rely on the right kind of nourishment—particularly prebiotic fibre. And this is exactly where asparagus shines: it’s rich in these fibres, making it one of your microbiome’s favourite foods.
Why asparagus is good for the gut
Asparagus contains a valuable combination of dietary fibre and bioactive plant compounds that are particularly interesting in the context of gut health. Of special note is its content of so-called fructans, especially inulin-type fructans (1–3).
Prebiotic effect: fuel for your gut bacteria
These fructans are classified as prebiotics—food components that cannot be digested by the human body but are instead utilised by gut bacteria in the colon.
Regular consumption of asparagus or other prebiotic foods may therefore support the growth of beneficial bacteria such as Bifidobacteria and Lactobacilli.
During the bacterial fermentation of these plant compounds, short-chain fatty acids (SCFAs) such as butyrate, propionate, and acetate are produced. These play a key role in gut health, as they help maintain the intestinal barrier, may have anti-inflammatory effects, and provide energy for the cells lining the gut.
More than fibre: Secondary plant compounds in asparagus
In addition to fructans, asparagus also contains a wide range of polyphenols. These secondary plant compounds have antioxidant properties and may also contribute to a healthy, diverse gut microbiome.
Note on tolerance: The fructans found in asparagus are fermentable fibres (FODMAPs) and may cause digestive discomfort in some individuals with sensitive digestion, particularly those with irritable bowel syndrome (IBS).
Now, on to the recipe:
Delicious, spring-like, and healthy: This asparagus quiche is both a showstopper and a delight for the palate.
Recipe for asparagus quiche
Ingredients for the dough:
- 150 g spelt flour
- 50 g oat flour

- 100 ml milk
- 100 g cottage cheese
- 1 tsp salt
- 1 tbsp dried thyme
- ½ tsp nutmeg (grated)
- 200 g green asparagus
- 150 g grated mountain cheese
- Cress & radish slices for garnish
Preparation:
- Mix all dry ingredients. Add olive oil and water and knead to a smooth dough.
- Form the dough into a ball and let it rest for approx. 15 - 20 minutes.
- Then roll it out, place it in a greased quiche pan, and press down the edges.
- Prick the bottom with a fork and pre-bake for 10 minutes in the oven at 180°C.
- For the filling, mix eggs with milk, cottage cheese, salt, and thyme, then add half of the grated cheese.
- Wash the asparagus, cut off the woody ends, and cut the rest into bite-sized pieces.
- Pour the filling into the pre-baked quiche first, then spread the asparagus pieces on top, and finally sprinkle with the remaining cheese.
- Bake the quiche for 40 - 50 minutes at 180°C top and bottom heat.
- Garnish the finished quiche with radishes & cress and enjoy!
Tip: Cress and other sprouts can be easily grown yourself. You can find instructions and more information here: Grow your own sprouts: superfood right from your windowsill
Why you should definitely try our asparagus quiche
You’re already familiar with the health benefits of asparagus. In addition, we’ve included two particularly microbiome-friendly ingredients in the pastry: oat flour and psyllium husks. Both provide valuable soluble fibre, which can support a healthy gut microbiome and help regulate digestion (4).
An important note: make sure to drink enough fluids, as fibre binds water.
The eggs and dairy products included in the recipe also provide high-quality protein and fat – both important components of a balanced meal. This combination may help promote a more stable blood sugar response and support longer-lasting satiety.
