All-plant viennoiserie in Les Épinettes

Boulangerie Pâtisserie La Mauvaise Herbe operates as an independent bakery along Avenue de Saint-Ouen, drawing neighborhood lines out onto the pavement for its morning bake. Two signs sit above the entrance, and morning runners often queue up early for the fresh loaves and pastries. The queue generally moves fast along the street, though parking nearby is awkward.

Entirely plant-based baking mirrors classic French shop stock. The pistachio croissant, almond croissant, and plain croissants are baked without dairy. Loaves include a crisp traditional baguette and olive bread fresh from the oven, alongside slices of vanilla flan, chausson aux pommes baked around a whole apple, and citrus tarts. You also find soft Nordic bread among eleven specialty loaves, chocolate brioche, and savory quiche.

Inside, the space is built primarily for takeaway business. There are two or three bar stools for eating on the spot, but there is no full dining room and no customer restroom. You can order hot drinks like a matcha latte to drink while perching there, and credit cards are accepted.

A simple traditional baguette costs one euro, and basic viennoiserie stays modestly priced, though sandwiches cost over six euros and raspberry tarts run nearly six euros apiece. Savory options also sell down faster in the late afternoon. You pay one euro eighty for an almond croissant, but a salad portion with lettuce, pasta, and cherry tomatoes can feel light for what it costs.

While pastry and bread pricing remains accessible, the smaller fruit tarts and savory items run noticeably higher for their size.

The pick list

What to bring home

  1. Pistachio croissant

    A dairy-free pastry that stands up to any traditional version. It rivals regular croissants.

  2. Croissant

    A 100% plant-based version that stays flaky on the outside and soft inside. Pick one up early before the morning batch sells out.

  3. Almond croissant

    The almond croissant has amazing flavor.

  4. Sandwiches

    Savory lunchtime options like the hearty Harrison, packed with plant-based fillings on bread. Choices thin out later in the day.

  5. Traditional baguette

    A crisp, fresh loaf that costs only 1 euro. It sells steadily to morning runners and locals.

Who is this for

Travelers with dairy allergies or plant-based diets who still want classic French croissants and patisserie will find exactly what they need here. It also fits morning walkers picking up fresh bread or a pistachio pastry in Les Épinettes.

Fromagerie Chambi, located one hundred meters away on Avenue de Saint-Ouen, supplies aged cheeses and dairy goods for travelers shopping for traditional cheese boards.

The verdict

While it lacks customer restrooms and seating beyond two bar stools, it delivers rare, fully plant-based versions of French viennoiserie and baguettes at everyday neighborhood prices.
