We heat olive oil in a large pan over medium heat.
We place the duck breasts skin side down and sear for about 3 minutes per side, until golden.
We add the butter, garlic and rosemary, season with salt and pepper and baste the duck.
We sprinkle with smoked paprika and deglaze with white wine.
We continue cooking for about 5 minutes, allowing the sauce to reduce.
In a separate pan, we sauté the mushrooms for 1 minute.
We add the peas and cook for another minute.
We season lightly and pour in the sauce from the duck pan.
We simmer briefly until the sauce binds with the vegetables.
We slice the duck breast and serve with the peas and mushrooms, spooning over the sauce.
