For the Asparagus
- 1 lb (450g) asparagus, trimmed
- 1 tablespoon olive oil
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1 teaspoon lemon juice (optional)
Grainy Mustard Pan Sauce
- 2 tablespoons butter
- 1 small shallot (or 1/4 onion), finely minced
- 1 garlic clove, minced
- 1/2 cup (120ml) chicken broth
- 1/2 cup (120ml) milk or half-and-half (or light cream)
- 2 tablespoons grainy Dijon mustard
- 1 teaspoon lemon juice (optional)
- Salt and pepper, to taste
Preparation Time
- Prep time: 10 minutes
- Cooking time: 45–60 minutes (mostly potato baking)
- Total time: About 55–70 minutes
Step-by-Step Instructions
Step 1: Bake the Potatoes
Preheat oven to 425°F (220°C). Scrub potatoes and dry well.
Pierce each potato 6–8 times with a fork. Rub with olive oil and salt.
Bake directly on the oven rack (or on a sheet pan) for 45–60 minutes, until very tender.
Step 2: Roast the Asparagus
When potatoes have about 15 minutes left, toss asparagus with olive oil, salt, and pepper.
Roast on a sheet pan at 425°F (220°C) for 10–12 minutes, until crisp-tender.
Finish with lemon juice if desired.
Step 3: Warm and Crisp the Chicken
Remove chicken meat from the bones (keep pieces intact if possible).
Heat a skillet over medium heat with a little olive oil or butter.
Add chicken skin-side down (if you have skin-on pieces) and warm for 3–5 minutes, until heated through and lightly crisp.
Step 4: Make the Grainy Mustard Pan Sauce
In the same skillet, melt butter. Add shallot and cook 1–2 minutes until softened.
Add garlic and cook 20 seconds.
Pour in chicken broth, scraping up browned bits. Simmer 2 minutes.
Stir in milk/half-and-half and grainy mustard. Simmer 2–3 minutes until slightly thickened.
Season with salt, pepper, and lemon juice if using.
Step 5: Assemble and Serve
Split baked potatoes and fluff the insides with a fork. Add toppings if you like.
Plate chicken with roasted asparagus and the baked potato. Spoon mustard pan sauce over the chicken (and a little on the potato, too).
Serving Suggestions
- Add a simple side salad with vinaigrette for freshness.
- Swap asparagus for green beans or broccolini if preferred.
- Sprinkle fresh herbs (parsley, chives, thyme) on top for a “finished” look.
- Serve with crusty bread to mop up extra pan sauce.
- For extra comfort: add a pat of butter and cracked pepper on the potato.
