Emergency Tarte Aux Oignons
1C 9-grain flour
Just under 1/4c good Olive oil
¼ C ice water
½ tsp salt
1tsp dry rosemary
1 Large Spanish/Red Onion
2 Large Portobello Mushrooms
3 good eggs
½ C Milk (if you use skim we can’t be friends)
½ C Yogurt
¼ C Crumbled Blue Cheese (or more if you like more)
Salt and Pepper to Taste
In a mixing bowl mix together the crust ingredients to make a pliable dough. Wrap in plastic and chill for 10 minutes.
Preheat oven to 325 degrees.
Cut Mushrooms in strips and Sauté with olive oil, salt and pepper. Caramelize the onion to your liking. Drain any liquid from the sautéed mushrooms and mix with the onion. Set aside.
With an electric beater (or whisk) beat the eggs until they increase a little in volume. Add milk, yogurt, and ricotta beating on medium speed. Taste and season. Remember no one likes an under-seasoned savory tart.
Take out the dough and roll it out to fit your baking vessel. If it’s cracking leave it out to warm up a bit. That should help. There’s no butter in there anyway so no point in keeping it so cold. Once your baking tin is lined with your dough, arrange the onion/mushroom mixture in there evenly, then scatter some crumbled blue cheese all over. Finally, pour the egg mixture over everything and give yourself a round of applause.
Pop your tart in the oven and bake 45-55minutes. When the tart is ready, it shouldn’t jiggle in the middle. You’ll know. How is it? Am I losing my mind or is the cracker-like crust kinda cool?
