Fatted Calf Crépinettes with Roasted Romano Beans and Two Sweet Potatoes
Golden crépinettes, blistered Romano beans, and two kinds of roasted sweet potato make a generous welcome-home supper. The Garnets turn soft and caramelized while the Japanese sweet potatoes stay dense and nutty, with a little lemon on the beans to balance the rich sausage.

Pan-Seared Fatted Calf Crépinettes
A steady sear browns the caul-fat wrapping without tearing it. Finishing in the oven cooks the thick centers gently while the vegetables finish roasting.
Ingredients
- 4 Fatted Calf pork crépinettes, approximately 6 ounces each
- 1 tablespoon ghee
Instructions
- Heat the oven to 425°F. Keep the crépinettes chilled until ready to cook, then gently blot their surfaces dry without disturbing the caul-fat wrapping.
- Heat the ghee in a large ovenproof skillet over medium heat. Add the crépinettes with space between them and cook for 4–5 minutes, until the undersides are golden brown. Work in batches if necessary.
- Turn carefully with a thin spatula and cook for another 3–4 minutes. Do not press down on them. Spoon off excess rendered fat if it begins to pool deeply.
- Transfer the skillet to the oven and cook for approximately 8–15 minutes, until a thermometer inserted sideways into the center registers 160°F for pork crépinettes.
- Rest for 5 minutes before serving.
Notes
- Follow the butcher’s instructions if supplied. If the filling contains poultry, cook to 165°F rather than 160°F.
- These are already seasoned sausages; do not salt them before tasting.
Roasted Romano Beans with Lemon
High heat gives the broad beans blistered patches while leaving them supple rather than mushy. Lemon added after roasting keeps the finish bright.
Ingredients
- 1 pound Romano beans, stem ends trimmed
- 1½ tablespoons olive oil
- ¼ teaspoon fine sea salt, plus more to taste
- ¼ teaspoon freshly ground black pepper
- 2 teaspoons fresh lemon juice
Instructions
- Dry the beans thoroughly. Toss with the olive oil, salt, and pepper on a rimmed sheet pan.
- Spread into a single layer and roast at 425°F for 15–20 minutes, turning once, until lightly blistered and tender enough to bite through easily.
- Toss with the lemon juice just before serving and adjust the salt.
Notes
- Keep slender beans whole as pictured; cut unusually long beans in half only if needed to fit the pan.
- Older, thicker beans may need several extra minutes to become tender.
Roasted Garnet and Japanese Sweet Potato Batons
Evenly sized batons let both varieties roast together. Plenty of pan space develops browned edges while preserving their contrasting creamy and chestnut-like interiors.
Ingredients
- 1 pound Garnet sweet potatoes
- 1 pound Japanese sweet potatoes
- 2 tablespoons olive oil
- ½ teaspoon fine sea salt, plus more to taste
- ¼ teaspoon freshly ground black pepper
Instructions
- Scrub the sweet potatoes and peel if desired. Cut lengthwise into irregular batons approximately ½ inch thick, keeping the thickness reasonably consistent.
- Toss with the olive oil, salt, and pepper. Divide between two rimmed sheet pans so the pieces sit in a single layer with space around them.
- Roast at 425°F for 30–40 minutes, turning after about 20 minutes and rotating the pans between racks.
- Remove individual pieces as they become tender through the center and deeply golden along the edges. Taste and add salt if needed.
Notes
- Expect browned edges and tender centers rather than the brittle crispness of deep-fried potatoes.
- If oven space is limited, consolidate the sweet potatoes onto one pan after they have shrunk and browned, freeing a rack for the beans.
Overall Timing / Workflow
The sweet potatoes take the longest and tolerate a short hold. Starting the beans and crépinettes later brings all three components to the table hot.
Instructions
- 0:00 — Heat the oven to 425°F. Cut and season the sweet potatoes.
- 0:15 — Put the sweet potatoes in the oven. Trim and dry the Romano beans.
- 0:30 — Turn the sweet potatoes and rotate their pans. Begin searing the crépinettes.
- 0:35–0:40 — Put the beans in the oven, consolidating the partly roasted sweet potatoes if necessary to make room.
- 0:40 — Transfer the browned crépinettes to the oven. Check the sweet potatoes and remove tender, caramelized pieces as they finish.
- 0:50–1:00 — Check the crépinettes with a thermometer and rest them for 5 minutes once cooked. Finish the beans with lemon and plate everything.
Notes
- Allow roughly 60–65 minutes from starting prep to serving. Pan crowding and crépinette thickness can extend the cooking time.
Plating
Three distinct sections preserve the simple presentation and keep the beans and sweet potatoes from sitting under the sausage juices.
Instructions
- Place one rested crépinette toward the upper edge of each warm plate.
- Arrange the Romano beans in a loose parallel bundle alongside it.
- Pile the orange and pale sweet potato batons together in the remaining space, keeping their browned surfaces visible.
- Serve immediately without an additional sauce.
Leftover Path
Separate storage allows the sausage to reheat thoroughly without overcooking the beans. A hot oven restores some texture to the sweet potato edges.
Instructions
- Refrigerate the crépinettes and vegetables in separate shallow containers within 2 hours of cooking. Use within 3–4 days.
- Reheat the crépinettes in a covered baking dish at 350°F until their centers reach 165°F, uncovering briefly at the end.
- Reheat the sweet potatoes on a sheet pan at 425°F for 10–15 minutes. Add the beans for the last 5–7 minutes, just until hot.
- Alternatively, slice the cold crépinettes and reheat thoroughly with the sweet potatoes for a next-day hash; fold in chopped beans at the end.
