Method

 

Roast the asparagus

1. Preheat oven to 400°F (or air fryer to 380°F).
2. Lay asparagus on a parchment-lined baking sheet.
3. Drizzle with olive oil and sprinkle with salt, onion powder, and garlic powder (if using).
4. Toss to coat.
5. Roast 12–15 minutes, depending on thickness, until vibrant green and lightly caramelized.

Make the Mushroom Cream Sauce

1. Heat olive oil (or ghee) in a small skillet over medium heat.
2. Add mushrooms and onions. Sauté 4–5 minutes, until softened and lightly browned.
3. Add garlic (if using) and cook another 30 seconds.
4. Stir in the coconut milk, thyme, sage, and salt. Bring to a gentle simmer.
5. In a separate small bowl, whisk arrowroot/tapioca with cold water to make a slurry.
6. Stir the slurry into the pan and simmer 1–2 minutes, until thickened into a silky sauce.

Stovetop “Roasted” Asparagus Instructions (Skillet Method)

(Add this as its own section in WPRM under “Notes” or “Additional Instructions”)

Stovetop Method (if you don’t want to turn on the oven)

1. Heat a large skillet over medium-high heat and add 1–2 tablespoons olive oil.
2. Once the oil is shimmering, add the trimmed asparagus in a single layer.
3. Sprinkle with sea salt, onion powder, and garlic powder (if using).
4. Sauté 3–4 minutes, allowing the asparagus to get lightly blistered.
5. Turn the heat down to medium, cover the skillet, and cook another 3–5 minutes until tender but still bright green.
6. Transfer to a plate and spoon the mushroom cream sauce over the top.

Tips for Stovetop Success

• For thicker asparagus, add 1 tablespoon water, cover, and steam for an extra minute.
• For thinner asparagus, skip the steaming step so it doesn’t soften too much.
• Cast-iron gives the best “roasted” flavor.
• Don’t overcrowd the skillet — cook in two batches if needed.

Storage & Reheat

Store: Keep asparagus and sauce in separate containers for 3–4 days.
Sauce Thickens: Coconut milk firms when chilled — totally normal.
Reheat: Warm gently in a skillet with a splash of water or broth.
Avoid Splitting: Don’t boil; keep heat low and stir slowly.
Microwave Tip: Cover and heat in short bursts to keep the sauce smooth.

Freezer Tips

Freeze Sauce: Freezes well for up to 2 months; whisk after thawing.
Freeze Asparagus: Only if cooked al dente; re-sear in a hot pan to revive texture.
Avoid Mushiness: Don’t freeze fully soft asparagus — it won’t hold its shape.
