How to make the best Brussels Sprouts gratin in air fryer/ oven? -Step by Step:
This Christmas Sprouts recipe comprises three simple steps. Roast the Brussels sprouts in the air fryer for 8-10 minutes. The secret to their deliciousness lies in the seasoning - Chilli salt from Cornish sea salt. If unavailable, craft your own blend by combining ½ teaspoon of garlic powder, onion powder, oregano, mild paprika, and salt. Alternatively, toss the sprouts in a bit of fajita or taco seasoning. Toss the Brussels sprouts with oil and chilli salt, then air fry at 180C for approximately 8 minutes. Prepare the easy white sauce, using my favourite béchamel sauce from my cauliflower cheese recipe. I like to use familiar flavours to entice everyone to reach for more. Assembling and Cooking: Arrange the sprouts in your deep serving dish. Pour the white sauce over them and top with white breadcrumbs or flavoured breadcrumbs for an extra layer of deliciousness. Air fry or oven-bake until the sauce is bubbly and the crumbs are golden brown. For Air Fryer Instructions: Place the assembled dish in the air fryer basket and air fry at 180C for about 10-12 minutes or until golden brown. For Oven Instructions: Preheat the oven to 220C/200C fan/gas 7. Bake the dish in the center of the oven for 20-25 minutes or until golden brown and bubbling. Allow it to rest for at least 10 minutes before serving.
Tips to make the best Brussels sprouts gratin
Roasting the Brussels sprouts unlocks their hidden sweetness and depth of flavour. Try this instead of boiling them. Don’t just season the sprouts with salt and pepper. Think flavours! I have used Chilli salt. You can sub with fajita or taco seasoning for a delicious mix. A creamy, cheesy sauce made of cheddar adds to the deliciousness. You can also swap for Gruyère and Parmesan to create a luxurious base. A simple breadcrumb topping adds texture and richness. For extra deliciousness, opt for flavored breadcrumbs or toss your white breadcrumbs with herbs before using them in the recipe. Choose the right sprouts to ensure a perfectly bubbly top. Variations: Add banana shallots, bacon, pancetta, or even chestnuts for a touch of savoury flair.
