- Bring a large pot of salted water to a boil.
- Add the cauliflower florets and cook for about 5 minutes, or until just tender but still a bit firm.
- Drain the cauliflower and transfer it to a large, ovenproof dish.
3. Cook the Bacon:
- In a medium pan, cook the chopped bacon over medium heat until it turns crispy.
- Remove from the pan and set aside, leaving the bacon fat in the pan.
4. Prepare the Sauce:
- In the same pan, add the butter to the bacon fat and melt over medium heat.
- Stir in the flour to form a roux and cook for about 2 minutes, until golden.
- Gradually whisk in the milk, ensuring there are no lumps.
- Continue cooking and stirring until the sauce thickens, about 5-7 minutes.

5. Assemble the Gratin:
- Pour the sauce evenly over the cauliflower.
- Sprinkle the remaining cheddar cheese on top.
- In a small bowl, mix the bread crumbs with a tablespoon of melted butter (optional) to help them brown better.

Cauliflower and bacon gratin FAQ:

What is the baking time for the gratin?

Bake the gratin in a preheated oven at 375°F (190°C) for approximately 25-30 minutes, or until the top is golden and bubbly.

How do I know when the cauliflower is done cooking?

Cook the cauliflower florets in boiling salted water for about 5 minutes. They should be tender but still slightly firm, as they will continue cooking in the oven.

Can I make this gratin ahead of time and store it?

Yes, you can prepare the gratin ahead of time. Assemble the dish, cover it tightly, and refrigerate for up to 24 hours before baking. You may need to add a few extra minutes to the baking time if it is cold from the fridge.

What can I use as a substitute for cheddar cheese?

You can substitute cheddar cheese with other melting cheeses such as Gruyère, Monterey Jack, or a combination of your favorite cheeses, although the flavor will vary.

What pan size should I use for this recipe?

A medium to large ovenproof dish (about 2-quart capacity) works well for this recipe. Ensure it's large enough to hold the cauliflower and sauce while allowing for some topping.

Tips:

- Choose a fresh, firm cauliflower without any brown spots for the best results.

- You can substitute turkey bacon for a leaner version of the dish.

- Use sharp cheddar cheese for a more intense flavor.

- For a gluten-free version, use gluten-free flour and breadcrumbs.

- Gradually add the milk while making the sauce to avoid lumps.
