Prep: 35 min | Cook: 1 hr 20 min | Total: 2 hrs 10 min
Cost: $17.04 total, $2.84 per serving
Ingredients
- 6 Sweet Onions (medium‑small, about 8‑10 oz each)
- 6 Tbsp Unsalted Butter (softened; can use salted butter if preferred)
- 2 Tbsp Smackalicious Seasoning Mix (store‑bought mix; optional – can replace with dry herbs)
- 1 roll Heavy‑Duty Aluminum Foil (use thick foil to avoid tearing)
- ½ tsp Salt (optional, adjust to taste)
Instructions
Preheat Oven
Set the oven to 375°F (190°C) and let it preheat while you prepare the onions.
Time: PT10M
Temperature: 375°F
Core the Onions
Using a sharp chef knife, cut off the root end of each onion, then make a shallow circular cut around the top to expose the inner layers. Remove the soft core with the tip of the knife, creating a small cavity.
Time: PT10M
Season Butter
In a small bowl, combine softened butter with the Smackalicious seasoning mix (or the dry herb substitute) and a pinch of salt. Mix until evenly incorporated.
Time: PT5M
Stuff the Onions
Spoon the seasoned butter into each onion cavity, pressing gently to fill the space completely. Ensure the butter reaches the deepest part of the cut.
Time: PT10M
Wrap in Foil
Tear a piece of heavy‑duty foil large enough to completely encase each onion. Place the butter‑stuffed onion in the center, bring the edges together, and seal tightly, making sure there are no holes.
Time: PT5M
Arrange on Baking Sheet
Place all wrapped onions on a baking sheet or glass dish pan in a single layer.
Time: PT2M
Roast the Onions
Bake in the preheated oven for 1 hour 20 minutes, or until the onions are very tender and the butter has melted into the layers.
Time: PT1H20M
Temperature: 375°F
Rest and Unwrap
Remove the baking sheet from the oven and let the onions rest for 5 minutes. Carefully open the foil packets (steam will be hot) and serve immediately.
Time: PT5M
