Ingredients Needed
To create this Roasted Cauliflower Cheese Lasagne, you'll need the following ingredients:
- Cauliflower: The centerpiece of the dish, roasted to perfection to bring out its sweetness and nuttiness.
- Salt and Black Pepper: These basic yet essential flavour enhancers are key for elevating the taste of your dishes. No food will ever be bland when these are used to season to taste.
- Low Calorie Olive Oil Spray: For a light roasting of the cauliflower, promoting a crispy texture without added fats and to grease the oven dish for baking.
- Milk: Forms the creamy base of the sauce. Opt for 2% (semi skimmed) milk for the right balance of creaminess without being too heavy. Skimmed milk is not recommend as it will not yield the same creaminess to the sauce.
- Vegetable Stock: Adds depth and richness. It's essential to use the correct ratio of stock cubes to water, as not all stock cubes are identical. Using too few can lead to a bland, watery broth, while too many may create a stock that's overly salty.
- Light Cream Cheese: For creaminess and a slight tang. Use Philadelphia or stores own brand.
- Cornstarch (Cornflour): Thickens the sauce to the right consistency.
- Dijon Mustard: Introduces a subtle tanginess.
- Onion Powder & Garlic Powder: Enhance the flavour of the lasagne
- Italian Seasoning: Brings in classic herby notes.
- Parmesan: Adds a savoury, nutty taste to the sauce.
- Pasta Sheets: The structural component of the lasagne, available in gluten-free varieties.
- Mature Cheddar Cheese & Mozzarella: These cheeses add a delicious golden melted cheese topping.
- Freshly Chopped Italian Parsley: Adds a final touch of freshness and color.
Gather these ingredients to prepare your lasagne, ensuring a flavourful and comforting dish.

The Perfect Low Calorie Alfredo Sauce
Crafting the perfect low-calorie Alfredo sauce for our Roasted Cauliflower Cheese Lasagne is all about selecting the right ingredients without compromising on the creamy, indulgent texture that makes Alfredo sauce so beloved. We use 2% semi-skimmed milk as the base, offering a delightful creaminess without the heaviness of full-fat milk. The addition of light cream cheese and a sprinkle of cornstarch works wonders, thickening the sauce while adding a rich, tangy flavor, ensuring the sauce is luscious yet not overly calorie-dense.
The sauce's flavor is deepened with a careful blend of garlic powder, onion powder, Italian seasoning, and a hint of Dijon mustard, creating a harmonious profile that complements the lasagne's layers. Parmesan cheese is the final touch, providing a savory, nutty quality that ties all the flavors together beautifully. This approach demonstrates that with thoughtful ingredient choices, you can create a lower-calorie Alfredo sauce that still promises to be a decadent and satisfying component of any dish.
Variations/Additions
Exploring variations and additions to your Roasted Cauliflower Cheese Lasagne can transform this classic dish into a new culinary experience each time you make it. Here are some creative ideas to customize your lasagne:
- Protein Boost: Incorporate slices of ham, shredded cooked chicken chicken, cooked sausage or cooked bacon between the layers for an added protein punch and a richer flavor.
- Cheese Varieties: Experiment with different cheeses for the topping. Swap out cheddar for smoked gouda, gorgonzola, or a sharp provolone to bring a new taste profile to your dish.
- Additional Vegetables: Enhance the nutritional value and texture by adding some additional vegetables, just be sure to saute or roast them before topping with the sauce. Options like wilted. spinach or roasted bell peppers would make a great addition.
- Spicy Twist: For those who enjoy a bit of heat, sprinkle some Cajun seasoning on the cauliflower before roasting, adding a spicy dimension that contrasts beautifully with the creamy sauce.
These variations not only add complexity and depth to the lasagne but also allow you to tailor the dish to your preferences or to what you have on hand in your kitchen.
