‘Campagnarde’ in French literally translates to ‘countryside’, so in creating this simple and delicious tarte dish I incorporated rustic French countryside flavors, and that is really what La Mangeoire is all about. When we recently revamped the interior and the menu at the restaurant it was to reflect our passion which is not any particular type of French cuisine, but instead ‘French Country Cooking’ which encompasses all of the delicious flavors and recipes that myself and owner Gerard Donato have experienced through years of travel and eating. This particular tarte, the Tarte Campagnarde, utilizes cremini mushrooms, red tomatoes, nutmeg, Ricotta and Swiss cheese to create an earthy, homey dish.

For the Dough

For the Batter
- Combine milk and heavy cream in a large saucepan and bring to a boil.
- Remove the skin on the surface and let cool for 15 mns
- In a mixing bowl combine the eggs and the egg yolk and whisk in the milk and the heavy cream mixture
- Add the pinch of nutmeg and the salt
For the Filling
- Wash the mushrooms and pat dry
- Sauté the mushrooms in the 3 tbsp of Canola oil until slightly tender, drain and reserve, disregard the liquid.

Frequently Asked Questions
Why does the tart shell need to be blind-baked before adding the filling?
The recipe calls for lining the tart shell with parchment and filling it with dried beans as weights, then baking at 375°F for 30–40 minutes before adding any filling. This pre-bake (blind baking) sets the pastry so it does not turn soggy from the custard batter poured on top of the mushroom filling.
Why does the dough need to be refrigerated twice — once before rolling and once after?
The first chill (at least 1 hour after mixing) allows the butter to firm back up and the gluten to relax, making the dough easier to roll. The second chill (at least 20 minutes after pressing the dough into the mold) re-solidifies the butter so the shell holds its shape and doesn’t shrink when it hits the hot oven.
Can I substitute Gruyère for the Swiss cheese?
Yes — the notes explicitly list Gruyère as a substitute if Swiss cheese is unavailable. Gruyère has a similar meltability and a nuttier, slightly more pronounced flavor that works well alongside the Parmesan and Ricotta already in the filling.

la moungetta semble délicieuse, Christian !
je la sers aussi dans mon restaurant pour me rappeler Toulouse ! Aldo
One tablespoon of salt in the batter? Seems like too much. And why the extra yolk after 6 eggs ? It seems superfluous.
Have you made it?
That much salt for four cups of dairy and six eggs doesnt seem like too much to me, especially for something to be served at room temperature.
