4 tbsp pan drippings fat – skimmed from roasting pan
2 tbsp unsalted butter – use as needed to reach 4 tbsp total fat
4 tbsp all-purpose flour
2 cups low-sodium stock
0.5 tsp kosher salt
0.5 tsp black pepper – freshly ground
Instructions
After roasting, set the pan over medium heat. Tilt and spoon off most of the fat, then measure out 4 tbsp pan drippings fat and return it to the pan.
Add unsalted butter if needed to reach a total of 4 tbsp fat, melting it and combining with the drippings.
Sprinkle in the all-purpose flour and whisk constantly to form a smooth roux. Cook until blond to light brown, 2–3 minutes, scraping up browned bits.
Gradually whisk in the low-sodium stock, starting with a small splash to loosen the fond, then adding the rest in a slow stream until smooth.
Bring to a simmer and cook, whisking occasionally, until glossy and thick enough to coat the back of a spoon, 5–8 minutes.
Season with the kosher salt and black pepper, adjusting to taste.
Strain through a fine-mesh sieve into a warm gravy boat for a smoother texture, if desired.
Rest 2 minutes to let bubbles subside, then serve hot.
