Why Roasted Vegetables with Pesto is a Winner

Pesto roasted vegetables offer a winning combination of taste and plenty of health benefits too:

  • Taste – The pesto adds a vibrant punch of extra flavour to vegetables. Roasting vegetables amplifies their flavour but the extra addition of the basil pesto really takes them to the next level.
  • Nutrient Powerhouse – Vegetables are packed with essential vitamins, minerals, and the all-important fibre, all crucial for overall health and blood sugar control.
  • Low Carb Delight – Most vegetables are naturally low in carbohydrates, making them a great diabetes-friendly option. Roasting helps further concentrate their sweetness without adding any extra carbs.
  • Fiber Fiber Fiber– Vegetables are full of soluble fibre which slows down the digestion of carbohydrates, helping to regulate blood sugar levels and promoting a feeling of fullness.

The Perfect Pesto

The beauty of this pesto veggie recipe lies in its adaptability. You can choose any vegetables you like to roast but you also have options when it comes to the choice of pesto. Here are some points to consider:

Homemade – Making your own pesto allows you to control the ingredients and sugar content. I always prefer a homemade option over shop bought (but I also often need to opt for convenience too!). Try my Spinach Pesto Recipe which is not only tasty but budget-friendly and can be frozen so you can be prepared and grab it when you need it.

Shop Bought Options: READ THE LABELS – always read the labels to understand exactly what is in your pesto. Be wary of cheap oils, added emulsifiers and sugars.

Nutty Options: Explore pesto recipes with different nuts. Pine nuts are a classic choice, but walnuts, almonds, or cashews can also add a slightly different flavour profile.

However, if you are catering for a vegetarian you will want to check your jar is clearly labelled as suitable for vegetarians or vegans. This is because most regular pesto is made with cheese which contains animal rennet (an enzyme extracted from the stomach lining of calves), making it not suitable for vegetarians.

What you will need for the Pesto Roasted Green Vegetables

While any vegetable can be roasted, some are particularly well-suited for those managing diabetes due to their low glycemic index (GI):

  • Cruciferous Veg: Broccoli, Brussels sprouts, and cauliflower are packed with fibre and nutrients, boasting a low GI.
  • All the Greens: Asparagus, courgette (zucchini), and green beans are excellent sources of vitamins and minerals while remaining low on the glycemic index.
  • Peppers and Carrots: Bell peppers and carrots offer a vibrant sweetness without spiking blood sugar due to their low carbohydrate content.

Cooking Tips for the Perfect Roasted Vegetables

To achieve perfectly roasted vegetables, consistency is key. Aim for evenly sized pieces to ensure they cook at the same rate.

Additionally, a high oven temperature of 220°C (or 200°C fan) is essential for achieving that coveted crispy exterior while keeping the vegetables tender on the inside.

Another secret for perfectly tender yet crispy roasted vegetables lies in spreading them out on a single layer on the baking sheet. I suggest using two baking trays. This allows for even heat distribution, preventing soggy vegetables and ensuring maximum flavour development.
