So I took the olive oil and chicken fat left over from baking the chicken tenderloins--about half a cup--and stirred it in with a cup of vegetable bouillon. Then I toasted a big poof of flour in a pan until it browned lightly, added a little of the liquid to make a paste, then added more liquid to blend and turned the heat up to simmer until it thickened. Then I tossed in some black pepper.
AND IT WORKED. Best gravy I've ever had.
And yes, I am totally bragging that I cooked without a recipe.
Only problem: Not enough gravy! I would've liked about half again as much for the pie. As is, though, everything got nice and moist. Next time I might cook extra chicken and use the rest for another recipe that doesn't need schmutz.
Queen of Gravy Chicken Pie
Take a pound or a pound and a half of chicken breasts or tenderloins. Lay them in a pan and generously coat them with olive oil so that they're dripping, but not swimming. Bake until done. Put them aside and pour off the oil and chicken fat mixture. You'll need half a cup to three-quarters of a cup for the gravy.
Obtain pie crust in the way of your people. (I use Stop & Shop brand.) Lay one round in a pie plate and layer in cooked vegetables (fresh or frozen) and finely chopped chicken.
Dissolve about a teaspoon of Better than Bouillon Vegetable Base with a cup of water. Add the olive oil/chicken fat mixture and heat to mix.
In a dry pan, toast a couple-few tablespoons of flour until lightly browned. (If you want more precise measurements, look up recipes for roux, since making roux is how I learned my flour-fu.) When the flour is browned, pour a little of the broth into the pan and stir to make a paste. Add the rest of the broth slowly, stirring to blend the flour with the liquid. Turn up the heat and simmer until the mixture thickens. Adjust seasonings to taste--I added three or four shoofs of black pepper.
Pour the gravy over the pie and let it sink into the layers of chicken and vegetables.
Add the top crust and bake at 425 degrees for about 25-35 minutes, or until golden brown.
Nom in good health.
