Is there anything more low carb than taking a wonderful vegetable and elevating it… by adding cheese? With this gratin recipe I haven’t bothered about low carb breadcrumb alternatives or even used my classic pork rind topping – cheese is enough!
Simply place the trimmed asparagus in a baking dish – and by trimmed I mean breaking the woody end of the stalk off each asparagus. Then mix together some melted butter, garlic, and dried thyme. What a combination of flavors! Pour it over the asparagus.
Season with salt and pepper, then roast in a preheated oven for 8-10 minutes. Cooking time depends on how thick your stalks of asparagus are, but at this point you are looking to have them just slightly tender.
Sprinkle over some shredded cheese (I used an Italian blend, but seriously – use your favorite!), and return the dish to the oven. Continue to cook until the cheese has melted and starting to turn golden brown. If the asparagus tips are cooking too quickly at this point, you could place it under the broiler (overhead grill) instead to speed things up.
Oh and a quick tip for serving – if you have the asparagus layered like I have – make sure everyone gets some from the top and some from the bottom. The top ones have the most cheese, but the lower layers are more buttery!
