Every exceptional dish begins with exceptional ingredients.

At Flagstaff House, each menu starts with a simple philosophy: source the finest ingredients available, beginning close to home whenever the season allows.

Throughout the year, our culinary team partners with Colorado farmers, ranchers, and artisan producers who share our commitment to quality and craftsmanship. These relationships allow us to showcase the character of the region while celebrating the ingredients at their peak.

When an ingredient cannot be sourced locally without compromising quality, we look farther afield, selecting producers who meet the same uncompromising standards. Every ingredient is chosen with intention, whether it comes from a neighboring farm or across the globe.

The result is a menu guided not by distance, but by quality, seasonality, and a deep respect for the ingredients themselves.

Sous Chef James Roberts joins us to explore the inspiration, technique, and story behind one of his latest creations.

Originally from New Orleans, for Chef James this dish is a reminiscence of a childhood spent duck hunting with his father, and enjoying Palisade peaches during summer visits to Colorado.

The Duck Breast begins with the quintessentially New Orleans Sazerac cocktail and takes it somewhere distinctly Colorado. At its center are ripe Palisade peaches, worked through the dish in several forms and paired with the cocktail’s signature notes. Bourbon finds its way into the peach glaze and reduction, Peychaud’s bitters season the compressed peaches and compote, and Pernod brings the anise character traditionally supplied by absinthe.

The duck is sliced and served with toasted brioche and a round of seared Caña de Cabra goat cheese, then finished with peach compote, red veined sorrel, and citrus begonias. Rich duck, tangy goat cheese, ripe peach, bitters, bourbon, and anise come together in a dish that is the story of Chef James, told on the plate.

Featuring the Cure Farms Squash Blossom.

Squash blossoms from are filled with a delicate salmon mousse, then baked in dill butter until golden. Executive Chef Chris Royster sets them over baby squash, poached in court bouillon before being seared, and a bright take on panzanella: cherry tomatoes marinated in dill, lemon, and Moscato vinegar, warmed with radish and finished with sourdough brioche croutons.

The plate comes together with another spoonful of dill butter, fresh dill, and cranberry hibiscus leaves, whose bitter, sour edge cuts through the richness and brings the garden back into focus.
