Seared Duck Breast with Cherry Gastrique and Wilted Spinach

Restaurant elegance, twenty-minute reality. This keto-friendly duck dinner delivers all the drama of a bistro plate without the fuss: a crisp-skinned duck breast rendered low and slow for perfect fat, sliced thin over a bed of garlicky wilted spinach, and draped in a glossy cherry-balsamic gastrique sweetened with a sugar-free sweetener instead of sugar. The sauce comes together in the same pan the duck was seared in, picking up all the fond for deep, tangy-sweet flavour in just a few minutes. This version is built with a lighter touch in mind: the duck is portioned modestly and rendered thoroughly so most of the excess fat is poured off, the spinach is wilted in just a touch of that rendered fat plus garlic, and the gastrique relies on vinegar, cherries and aromatics rather than butter or cream for its richness. It's a satisfying, protein-forward plate that's gentle on the stomach, full of bright acidity, and easy enough to pull off on a weeknight.

Ingredients

• 2 each (5-6 oz each)Duck breast, skin on, scored in a crosshatch pattern
• 0.5 tspsalt, plus more to taste
• 0.25 tspblack pepper, freshly ground
• 1 cupFrozen pitted cherries, thawed, halved if large
• 3 tbspbalsamic vinegar
• 0.25 cupchicken broth, low sodium
• 1 tbspGranulated sugar-free sweetener, erythritol or allulose blend
• 1 smallshallot, finely minced
• 3 clovesgarlic, 2 minced for spinach, 1 minced for sauce
• 1 sprigfresh thyme, or 1/4 tsp dried
• 6 cupsbaby spinach, packed
• 1 pinchred pepper flakes, optional
• 0.5 eachlemon, for a squeeze of juice

Method

1. Pat the duck breasts dry and score the skin in a crosshatch pattern, cutting through the fat but not into the meat. Season both sides generously with salt and pepper.
2. Place duck skin-side down in a cold cast iron skillet, then set over medium heat. Let the fat render slowly, pressing occasionally with tongs for even contact. 8:00
3. Once the skin is deep golden and crisp and most fat has rendered, pour off all but 1 tablespoon of fat from the pan (reserve a little for the spinach). Flip the duck and sear the second side for 2-3 minutes for medium-rare. 3:00
4. Transfer duck to a cutting board to rest for 5 minutes before slicing; it will finish cooking as it rests. 5:00
5. While the duck rests, pour off all but about 1 teaspoon of the duck fat from the skillet. Add the minced shallot and cook over medium heat until softened. 1:30
6. Add the cherries, balsamic vinegar, chicken broth, sweetener, 1 clove minced garlic and thyme to the skillet. Simmer, stirring occasionally and scraping up any browned bits, until the sauce thickens slightly and coats the back of a spoon. 5:00
7. Remove the thyme sprig, stir in a squeeze of lemon juice, and season the gastrique with a pinch of salt to taste.
8. Meanwhile, heat the reserved teaspoon of duck fat in a large skillet over medium heat. Add remaining 2 cloves minced garlic and red pepper flakes, and cook until fragrant. 1:00
9. Add the spinach in batches, tossing with tongs until just wilted. Season with a pinch of salt and remove from heat. 2:00
10. Slice the rested duck breasts thinly on the bias. Divide the wilted spinach between two plates, fan the duck slices on top, and spoon the warm cherry gastrique generously over the duck.
