## Cast-Iron Pork Tenderloin with Garlic and Parsley

A hot sear gives the lean pork a browned exterior, while a short oven finish keeps the center juicy. Garlic and parsley complement the vegetables without introducing a separate sauce.

### Ingredients

- 1 lb pork tenderloin, silver skin removed
- 1 tbsp ghee
- 3 cloves garlic, lightly crushed
- 3/4 tsp kosher salt, plus more to taste
- 1/4 tsp freshly ground black pepper
- 2 tbsp roughly chopped flat-leaf parsley

### Instructions

1. Heat the oven to 425°F. Pat the pork dry, tuck the thin tail underneath and season with salt and pepper.
2. Heat a cast-iron skillet over medium-high heat. Add the ghee and sear the pork for 5–7 minutes total, turning to brown all sides.
3. Reduce the heat, add the garlic and roll it through the fat for 30 seconds. Transfer the skillet to the oven.
4. Roast for 8–15 minutes, checking early, until the thickest part reaches 145°F.
5. Rest on a board for 5 minutes, then slice across the grain into 1/2-inch medallions. Spoon over the rested juices and cooked garlic, and scatter with parsley.

### Notes

- Temperature, rather than pinkness alone, determines doneness; pork should reach 145°F and rest at least 3 minutes.

## Roasted Japanese Sweet Potatoes

Roasting whole preserves the red skins and concentrates the dense, chestnut-like sweetness of Japanese sweet potatoes.

### Ingredients

- 4 small Japanese sweet potatoes, about 5–6 oz each
- 1 tsp olive oil
- 1/4 tsp kosher salt

### Instructions

1. Heat the oven to 425°F. Scrub and dry the potatoes, then prick each a few times with a fork.
2. Rub lightly with olive oil and salt. Place on a lined baking sheet.
3. Roast for 45–65 minutes, turning once, until a thin knife slips through the centers without resistance.
4. Keep whole for serving, or split just before eating.

### Notes

- Larger potatoes may need 75 minutes; start them before the other components.

## Garlicky Green Beans, Snap Peas and Cherry Tomatoes

A brief blanch cooks the beans evenly before they meet the skillet. Tomatoes soften into a light coating while the snap peas retain their crunch.

### Ingredients

- 10 oz green beans, trimmed
- 6 oz sugar snap peas, strings removed
- 10 oz mixed-color cherry tomatoes
- 1 tbsp ghee
- 3 cloves garlic, thickly sliced
- 2 tsp fresh lemon juice
- 2 tbsp flat-leaf parsley leaves
- to taste kosher salt and black pepper

### Instructions

1. Bring a pot of salted water to a boil. Blanch the green beans for 3 minutes, then drain and dry thoroughly.
2. Heat the ghee in a wide skillet over medium-high heat. Add the green beans and cook for 2 minutes, letting a few spots brown.
3. Add the snap peas and tomatoes. Cook for 3–4 minutes, tossing occasionally, until the peas are crisp-tender and some tomatoes begin to split.
4. Lower the heat, add the garlic and cook for 1–2 minutes without letting it burn.
5. Remove from the heat. Add lemon juice, salt, pepper and parsley, tossing gently so most tomatoes remain whole.

## Cast-Iron Sausages

A short covered steam cooks the sausages through gently; browning afterward produces taut, golden skins without splitting them.

### Ingredients

- 4 fresh mild Italian pork sausages, about 3–4 oz each, certified gluten-free
- 1 tsp ghee
- 1/3 cup water

### Instructions

1. Place the sausages and water in a skillet. Bring to a gentle simmer over medium heat, cover and cook for 7–9 minutes, turning once.
2. Uncover and let the remaining water evaporate. Add the ghee and brown the sausages over medium heat for 6–10 minutes, turning regularly.
3. Check that the centers reach 160°F. Rest for 3 minutes before serving whole.

### Notes

- Do not prick the casings; keeping them intact helps retain the juices.

## Husk-Roasted Summer Corn

The husks trap steam around the kernels, keeping the corn juicy while their outer layers toast and char.

### Ingredients

- 4 ears fresh sweet corn in the husk
- 2 tsp extra-virgin olive oil
- to taste flaky salt

### Instructions

1. Heat the oven to 425°F. Peel back the husks without detaching them, remove the silk and fold the husks back around the ears. Trim loose, dry ends.
2. Place on a baking sheet and roast for 25–30 minutes, turning once, until the kernels are tender and the husks have browned.
3. For darker husks, broil briefly on a foil-lined tray, turning frequently and watching continuously. Keep the husks well away from the heating element.
4. Let stand for 3 minutes. Peel back the husks and finish the kernels with olive oil and salt.

### Notes

- For a grill version, cook over medium heat for 20–25 minutes, turning frequently and moving away from flare-ups.

## Roasted Summer Ratatouille with Basil

Roasting the vegetables in a roomy layer gives the eggplant and zucchini browned edges instead of a watery texture. Tomatoes bind everything into a light, chunky sauce.

### Ingredients

- 1 small eggplant, about 12 oz, cut into 1-inch cubes
- 2 small zucchini, cut into thick half-moons
- 1 red bell pepper, cut into 1-inch pieces
- 1 small yellow onion, diced
- 12 oz ripe tomatoes, roughly chopped
- 3 cloves garlic, sliced
- 3 tbsp olive oil, divided
- 1 tsp kosher salt, divided, plus more to taste
- 1/4 tsp freshly ground black pepper
- 1 tsp red wine vinegar
- 1/3 cup loosely packed basil leaves, torn

### Instructions

1. Heat the oven to 425°F. Toss the eggplant, zucchini and bell pepper with 2 tablespoons olive oil and 1/2 teaspoon salt. Spread across a large sheet pan without crowding.
2. Combine the onion, tomatoes, garlic, remaining olive oil, remaining salt and pepper in a shallow baking dish.
3. Roast both dishes for 25–30 minutes, stirring once, until the vegetables have browned edges and the tomatoes are bubbling and softened.
4. Fold the roasted vegetables into the tomato mixture. Return to the oven for 10–15 minutes, until the eggplant is completely tender but the pieces still hold their shape.
5. Stir in the vinegar, adjust the salt and fold in most of the basil. Scatter the remaining basil over the top.

### Notes

- If the tomatoes release a lot of liquid, roast the tomato mixture a little longer before combining it with the vegetables.

## Overall Timing / Workflow

The long-roasting vegetables start first, leaving the final stretch for the meats and quick green vegetable sauté.

### Instructions

1. 0:00 — Heat the oven to 425°F and start the sweet potatoes.
2. 0:10 — Prepare the ratatouille and put its two pans in the oven, leaving space for air circulation.
3. 0:25 — Add the corn. Trim the green vegetables, blanch and dry the beans, and season the pork.
4. 0:40 — Combine the ratatouille vegetables and tomato mixture for their final roast. Start the sausages on the stovetop.
5. 0:45 — Sear the pork in a separate ovenproof skillet, then transfer it to the oven. Check the potatoes, corn and ratatouille and remove each as it becomes tender.
6. 0:55 — Brown the sausages and cook the green bean mixture in another skillet. Remove the pork when it reaches 145°F and rest it.
7. 1:05–1:20 — Finish the vegetables with herbs and acid, slice the pork and serve. Allow extra roasting time if the oven is crowded or the sweet potatoes are large.

### Notes

- The ratatouille and sweet potatoes can wait loosely covered for 15–20 minutes; cook the green vegetables last.

## Plating

Keeping the components in distinct groups preserves their textures and echoes the generous cast-iron presentation.

### Instructions

1. Use warm platters or clean, warm cast-iron skillets rather than pans that are still searing-hot.
2. Fan the pork slices along one side of a platter, place the sweet potatoes through the middle and spoon the beans, peas and tomatoes alongside. Add the pork juices, garlic and parsley over the meat.
3. Arrange the sausages on a second platter with the corn still partly wrapped in its toasted husks. Spoon the ratatouille beside them and finish with basil.
4. Serve family-style, letting everyone take portions from both platters.

## Leftover Path

Separate storage lets the pork reheat gently while the vegetables and sausages can take stronger heat.

### Instructions

1. Refrigerate leftovers in shallow, covered containers within 2 hours. Remove the corn husks before storing and keep the meats separate from the vegetables. Use within 3–4 days.
2. Reheat pork slices covered with a splash of water or their juices over low heat. Reheat sausages, potatoes and vegetables separately; bring reheated leftovers to 165°F.
3. For another meal, slice the sausages and cut the corn from the cobs, then warm them with the ratatouille. Serve with the remaining sweet potatoes.
4. Use thinly sliced cold pork with the leftover green vegetables as a lunch salad, adding fresh lemon juice and olive oil.
