Loaded Cauliflower Casserole Tips
- I recommend adding fresh dill, it makes the casserole very delicious.
- Try not to boil cauliflower too long, we don’t want a very soft vegetable, 10 minutes of boiling is sufficient. The cauliflower will still be baking in the oven, so it will become softer.
- Remove the sauce from heat before adding cheddar cheese, this will prevent the cheese to curdle. We want a smooth, silky sauce.
- You can also use butter instead of bacon dripping.
- What to serve it with? Loaded cauliflower casserole is a great addition to any meal, it can be served for holidays like Thanksgiving or Christmas with Paprika Slow Cooker Chicken or Homemade Garlic mashed Potatoes.

Cheesy Cauliflower Casserole FAQ’s
Yes, any non-dairy milk will be great to make the sauce for instance: soy milk, oat milk, almond milk or coconut milk.
You can store a cauliflower cheesy casserole in the refrigerator for about 3 to 5 days. Follow these steps to ensure proper storage: Allow the casserole to cool down to room temperature before refrigerating. Hot foods can raise the temperature inside your fridge and affect other items. Transfer the casserole to an airtight container or cover it tightly with plastic wrap or aluminum foil. This helps prevent moisture loss and prevents the casserole from absorbing odors from other foods in the fridge.
I like using these meal-prep containers which comes in 3 rectangular sizes.
No, you don’t have to cover the dish for baking in the oven.
