Instructions
Prepare the Vegetables
Preheat oven to 375°F (190°C).
Bring a large pot of salted water to a boil.
Add broccoli and cauliflower and blanch for 3–4 minutes until slightly tender but still firm.
Drain well and set aside.
Make the Cheese Sauce
In a saucepan, melt butter over medium heat.
Add minced garlic and sauté for 30 seconds until fragrant.
Stir in flour and cook for 1–2 minutes to form a smooth roux.
Slowly whisk in milk, ensuring no lumps form.
Cook for 4–5 minutes until the sauce thickens.
Lower heat and add Dijon mustard, salt, pepper, and nutmeg.
Stir in cheddar cheese (and mozzarella if using) until fully melted and smooth.
Remove from heat.
Assemble the Bake
Place the drained broccoli and cauliflower in a large baking dish.
Pour the cheese sauce evenly over the vegetables and gently mix.
Add Topping
Mix breadcrumbs with melted butter and sprinkle over the top.
Add Parmesan or flaked almonds if using.
Bake
Bake for 25–30 minutes until golden, bubbling, and slightly crisp on top.
Let rest for 5–10 minutes before serving.
Garnish with fresh herbs.
Tips
Do not overboil the vegetables; they should remain slightly firm before baking.
Whisk the sauce continuously while adding milk to avoid lumps.
Use freshly grated cheese for a smoother, creamier sauce.
Warm milk slightly before adding to the roux for easier blending.
Adjust sauce thickness by adding more milk if too thick or cooking longer if thin.
Add cheese off heat to prevent graininess.
Let the bake rest before serving so the sauce sets properly.
For extra flavor, roast the vegetables instead of boiling them.
Use a mix of cheddar types for deeper flavor complexity.
Toast breadcrumbs lightly before baking for extra crunch.
