Roasted Brussels Sprouts with Manchego Cheese Sauce

Brussels Sprouts in Manchego deserves more recognition. When roasted and finished with a creamy Manchego sauce these compact cabbages become an elegant, low‑carb side that pairs well with meats, poultry and holiday mains. Brussels sprouts have been cultivated in northern Europe for centuries, and their name reflects an association with the Brussels region. They are related to broccoli, kale and collards and are rich in vitamin C, vitamin B6, folate and vitamin K. If you take blood thinners, consult your doctor about serving leafy brassicas and cheeses, since high vitamin K can interfere with anticoagulant therapy.

Most commercial production in Europe comes from the Netherlands, Germany and the United Kingdom. The French introduced Brussels sprouts to North America, and today most U.S. production is in California. Many frozen preparations use a large share of the crop, but home‑roasted sprouts are far superior in texture and flavor. Beyond their vitamin content, cruciferous vegetables like Brussels sprouts have been studied for potential protective effects against certain cancers.

Choosing the Right Cheese

For this recipe we use authentic Manchego, a sheep’s‑milk cheese from the La Mancha region of Spain. Manchego is firm, buttery and often shows small irregular holes similar to Swiss; it melts beautifully without overpowering the dish. The cheese is sold at various ages — from young (fresco) to cured and aged — and the flavor grows more assertive with time. For this sauce we recommend a mid‑aged Manchego (curado), which brings a sweet, nutty backbone without becoming too sharp. When combined with a small amount of grated Parmesan, the sauce gains extra depth and a pleasant savory edge.

To keep the recipe low in carbohydrates, the sauce uses almond flour in place of wheat flour to create a roux. Heavy cream yields a rich, velvety texture; substitute part half‑and‑half if you prefer a thinner sauce, but expect a small change in the nutrition profile. Use only a modest amount of added salt because the cheeses contribute saltiness.

Preparation Tips

We use shallots instead of garlic in the sauce because their mild, sweet onion flavor complements Manchego without masking it. Lightly sauté the shallots in butter until translucent, then whisk in almond flour to form a light roux. Slowly add the cream and cook on medium‑low until the sauce thickens. Stir in thyme, grated Parmesan and about half of the Manchego until melted; save the remaining Manchego to top the dish before the final bake.

Roasting the sprouts first deepens their flavor and creates caramelized edges. Toss halved sprouts with extra‑virgin olive oil, salt and pepper and roast at high heat until they develop browned, crisp tips — this contrast of texture makes the creamy sauce more satisfying. After pouring the cheese sauce over the roasted sprouts, finish the casserole briefly in the oven so the top becomes golden and bubbly. Shavings of Manchego added just before serving lift both presentation and taste.
