Tom's Morningside Open-Faced Hot Turkey Sandwich with Flash Pan-Gravy
Blue Plate Specials
If you have ever found yourself sitting at a Formica counter at two in the morning, nursing a bottomless cup of coffee and listening to the rhythmic clang of a spatula against a flat-top, you know the soul of the American diner. This open-faced sandwich pays homage to the working-class heroes of Morningside Heights, ditching aristocratic pretense for thick bread, savory griddle-steamed turkey, and a deluge of rich, salty flash gravy. You do not need a commercial flat-top to recreate this salvation at home. You just need your heaviest cast-iron skillet, a stiff metal spatula, and the confidence of a short-order veteran working a Sunday morning rush.
Before you start
Bring the deli turkey to room temperature for ten minutes.
Dropping a pound of cold meat into the skillet will instantly crash the temperature of the cast iron, resulting in a boil rather than a proper griddle-steam.
Ingredients
- unsalted butter3 tbsp
- all-purpose flour3 tbsp
- low-sodium chicken broth1 1/2 cup
- roasted poultry base1 tsp
- Gravy Master or Kitchen Bouquet1/2 tsp
- coarse black pepper1/4 tsp
- unsalted butter2 tbsp
- thick-cut white bread slices4 large
- deli-sliced oven-roasted turkey breast3/4 lb
- low-sodium chicken broth1/4 cup
- mashed potatoes1 cup
- jellied cranberry sauce1/4 cup
Method
- 01
Melt three tablespoons of butter in a small saucepan over medium heat and aggressively whisk in the flour.
Cook the roux for about sixty seconds until it smells nutty and the raw flour taste is completely cooked out.
- 02
Gradually pour in one and a half cups of chicken broth while whisking constantly to prevent lumps.
Whisk in the poultry base, black pepper, and Gravy Master, bringing the mixture to a rapid simmer for two to three minutes until it thickens enough to coat the back of a spoon, then reduce heat to the lowest setting just to keep it warm.
- 03
Place a large cast-iron skillet over medium-high heat until genuinely hot.
Lightly butter one side of each slice of Texas Toast and drop them butter-side down into the dry pan for two minutes to build a crispy structural foundation, then remove and arrange on two heavy plates, toasted-side down.
- 04
Drop the sliced turkey directly into the hot cast-iron skillet and immediately pour the remaining quarter cup of chicken broth over the meat.
It will hiss and spit violently, which is exactly what you want.
- 05
Grab a stiff metal spatula and aggressively chop and turn the meat in the pan as the broth steams it.
This technique, known as the scrape, is the quintessential diner move; it releases the fond and heats the meat uniformly in seconds without drying it out.
- 06
Divide the hot, chopped turkey over the waiting bread and drown the entire affair in generous ladles of the flash gravy.
Serve immediately alongside a scoop of mashed potatoes cratered with gravy and a slice of jellied cranberry sauce.
Notes
The scrape is your secret weapon for authentic diner texture.
Commercial griddles rely on aggressive spatula work; mimicking this in cast iron deglazes the pan and warms lean deli meat rapidly without turning it leathery.
Do not skip the roasted poultry base.
Since you are not working with fresh pan drippings from a Sunday roast, a commercial flavor base is the only way to replicate the hyper-palatable, savory punch of authentic diner gravy.
