Tips from the EatingWell Test Kitchen
These are the key tips we learned while developing and testing this recipe in our Test Kitchen to make sure it works, tastes great and is good for you too!
- Tools that can be helpful in the prep work include a mandoline for easily slicing the butternut squash and a microplane for finely grating the garlic, which ensures it distributes evenly in the cream.
- You can substitute the squash with Yukon Gold potatoes and replace the shredded mozzarella with an Italian cheese blend.
- Thoroughly drain the sun-dried tomatoes. Excess oil from the tomatoes can make the casserole greasy.
Nutrition Notes
- Butternut squash is the star of this dish and is packed with vitamins and minerals. The orange color tells us that it is high in beta-carotene, a nutrient that is important for fighting inflammation and also is converted to vitamin A to aid in immunity. Butternut squash also contains fiber for digestive health and to support a healthy microbiome.
- Garlic is rich in anti-inflammatory compounds and has been studied for its role in lowering cholesterol and reducing blood pressure. One important compound in garlic, allicin, is activated when garlic is crushed or cut, so it’s better to chop your garlic before consuming.
- Sun-dried tomatoes concentrate the nutrients in tomatoes, as the water is removed. These types of tomatoes are high in a compound called lycopene, which can help reduce inflammation that contributes to obesity, type 2 diabetes and cancer.
