They are extremely easy to make, bake or roast, and serve! …But this one is different.

The key ingredient in this one is the Italian prosciutto which gives the vegetables a subtle, smoky flavor while not being overpowering.  It makes a world of difference in flavor!

 It’s SO GOOD!!  Everyone will ask, what is the hidden flavor? 

Plus, since everyone LOVES cheese on a casserole, the addition of Parmesan cheese adds more flavor without adding a lot of fat and calories.

A win-win for everyone!

How to make Roasted Sweet Potatoes Squash Casserole? (*full recipe card below!)

This recipe is very easy. Plus, the prep work is only in the chopping of these veggies: onions, carrots, sweet potatoes, yellow squash, brussels sprouts and cauliflower. 

Quick Directions To Make This Healthy Casserole:

  1. Grab your casserole baking dish. Spray it with cooking spray.
  2. Scatter all the vegetables.
  3. Top them with all the seasonings, and olive oil.
  4. Roast for 20 minutes, remove and with a spatula flip them over to roast them evenly, and return back into the oven for additional 20 minutes or longer.
  5. Remove, scatter with grated parmesan cheese on top. (full ingredients and instructions are in our “printable” recipe card below!)

QUICK TIP! You may be able to find some of these vegetables already cleaned and chopped for you, making the prep time practically effortless and quick. 

To Make Ahead? Yes, you can prepare this dish one day ahead. Cover and keep it chilled until your ready to roast it and serve. Or, roast it a day earlier, then pop it into a preheated oven at 350F degrees to reheat for about 15 minutes or longer.

For Dietary Restrictions: Use vegan cheese, instead of parmesan cheese. Omit the butter, and add additional extra virgin olive oil to keep the veggies moist.

Can we use pancetta or bacon in place of prosciutto? Yes, of course. Scatter about 2 to 4 ounces of cubed, uncured pancetta, or bacon into the mixture.

  1. Love the prosciutto in these beautiful vegetables! This is a side dish that I wouldn't feel guilty about eating. Roasting seems to bring out flavors that other methods of cooking can't. Delicious! 🙂

    1. We feel te same way! My husband encourages me to add te prosciutto to many dishes like this, and we have been hooked for years. Thanks and have a great weekend!!

  2. I agree with Sue's comment – we eat roasted vegetables often but the addition of prosciutto has my attention! So pretty to – thanks Anna and Liz!

  3. Roasted vegetables in one of my favourite dishes and with the addition of sweet potatoes. This is a real keeper for me!

    1. We agree, we made this so many times and with different veggies but it's always better with sweet potatoes added in there.
