In a heated cast iron skillet, add raw walnuts and dry roast for 3 to 5 minutes, then allow to cool.
Thoroughly wash Brussels sprouts and pat them dry with paper towels. Trim the bottom end, remove any wilted leaves, and cut in half.
Pour oil and heat the cast iron skillet at 248°F (120°C). Add onions and sauté at 140°F (60°C) until tender and translucent.
Place Brussels sprouts cut side up, then season with half of the garlic, salt, and black pepper.
Once the opposite side starts to soften or after 5 minutes, turn the Brussels sprouts cut side down. Sprinkle the remaining garlic, salt, and black pepper. Allow the Brussels sprouts to absorb the flavors of the sautéed onions for 1 to 2 minutes.
Remove the sautéed onions before they start to burn and continue to cook the Brussels sprouts, cut side down for 3 to 5 minutes at an increased heat of 248°F (120°C).
At the last 30 seconds, add dried cranberries, dry roasted walnuts, fresh thyme, and freshly squeezed orange juice, then gently stir.
Turn off the heat once the Brussels sprouts are slightly golden and tender to the bite. Serve with the remaining fresh orange.
Notes
Use fresh quality ingredients from the firm fresh white onions, juicy orange, fresh thyme, firm Brussels sprouts, and newly opened packages of raw walnuts and dried cranberries.Use a cast iron skillet or a heavy-bottomed pan to avoid burning the raw walnuts, onions and Brussels sprouts.
