Chicken: 1.5 lbs (680g) boneless, skinless chicken breasts. Quality matters here. Get decent chicken; it makes a difference. Free range, if you can.
Olive Oil: 1 tbsp (15 ml) .
Onion: 1 medium, chopped (about 1 cup / 150g ).
Garlic: 2 cloves, minced.
Broccoli: 1 head, cut into florets (about 4 cups / 400g ). Fresh is best; don't even think about frozen!
Butter: 4 tbsp (57g) unsalted + 2 tbsp (28g) unsalted (for crumb). Use proper butter, not spread.
Flour: 1/4 cup (30g) all-purpose.
Milk: 3 cups (720 ml) whole. Full fat is where the flavor's at.
Dijon Mustard: 1/2 tsp .
Nutmeg: 1/4 tsp ground.
Sharp Cheddar Cheese: 8 oz (225g) , shredded (about 2 cups ). Buy a block and grate it yourself, yeah? Pre-shredded cheese just doesn't melt right.
Panko Breadcrumbs: 1 cup (100g) .
Fresh Rosemary: 1 tbsp , finely chopped.
Parmesan Cheese: 1/4 cup (30g) , grated.

I like to start with the chicken and then do all the veggies before moving onto cheese sauce, so I've grouped it that way!

Essential: Salt & freshly ground black pepper, to taste. Don't skimp!

Frequently Asked Questions

Can I make this casserole ahead of time? I'm a busy bee like everyone else, you know!

Absolutely! You can assemble the entire casserole, right up to adding the crumb topping, cover it tightly with foil or cling film, and refrigerate it for up to 24 hours. Add the crumb topping just before baking. It's a brilliant way to get ahead if you're juggling a million things - like most of us are!

What are some good casserole dishes to use for baking this? Does size matter?

A 9x13 inch (23x33 cm) baking dish is ideal for this recipe, ensuring everything cooks evenly. You can use glass, ceramic, or metal, but keep in mind that glass dishes may require a slightly longer baking time.

Size does matter; a smaller dish will result in a thicker casserole that might take longer to cook, while a larger dish might spread the ingredients too thin and lead to a drier result.

Help! I don't have Panko breadcrumbs. What can I substitute in the rosemary crumb topping?

No worries, we've all been there! You can easily substitute crushed crackers like Ritz, regular breadcrumbs, or even crushed cornflakes. The Ritz crackers would bring in a fab flavor! Just ensure whatever you use is relatively dry and crumbs well.

You might want to adjust the amount of melted butter slightly depending on how absorbent your substitute is.

Is there a vegetarian alternative for this casserole? I'm trying to cut down on meat like my doctor suggested...

Certainly! To make this vegetarian, simply replace the chicken with an equal amount of cooked white beans (like cannellini or Great Northern) or extra firm tofu, cubed and lightly browned. Both options provide a lovely creamy texture and hearty protein, ensuring you don't miss the meat.

You might also want to add some extra vegetables, like mushrooms or bell peppers, for added flavor and nutrients.

How long will leftovers keep, and what's the best way to reheat this? I always end up with too much, like a proper Sunday roast!

Leftover chicken, broccoli, and cheddar casserole will keep in the refrigerator for 3-4 days when stored in an airtight container. To reheat, you can microwave individual portions, but for the best results (and to keep the topping crispy), reheat in a preheated oven at 350°F (175°C) for about 15-20 minutes, or until heated through.

A little splash of milk can help keep it moist too.

I want to add a little oomph to this recipe; what are some ways I can add a bit of a flavor kick to these good casserole dishes?

If you're looking to spice things up, try adding a pinch of red pepper flakes to the cheese sauce for a little heat. Using pepper jack cheese in the sauce, or adding a dollop of hot sauce before baking, are great ways to add more flavour.

You can also introduce sun-dried tomatoes or some sautéed mushrooms to the chicken and broccoli mixture for an earthy, umami boost.
