Is broccoli a Superfood?

Absolutely! Being part of the same cruciferous family like cauliflower, Brussels sprouts, and cabbage, broccoli is considered a real health bath. Studies have shown that 100 grams of broccoli intake fulfill the human body with the needed daily dose of vitamin C.

Besides a concentrated dose of vitamin C, it is also a good source of vitamins of group B and K. The broccoli is likewise rich in mineral salts such as zinc and iron. This vegetable is strongly recommended in consumption to those suffering from diabetes and heart illnesses due to its antioxidant properties.

How to choose broccoli?

The first thing to pay attention to when buying broccoli is the color. The more uniform and intense is the green, the fresher the vegetable is. Yellowish spots indicate that it has been harvested not so recently and that it is not the freshest. Also, observe the stalk. If the color of the edge differs from its middle part, it means that it is dehydrated, which indicates the fact that broccoli is not very fresh. Lastly, the consistency of the vegetable is also an indicator. It should be firm upon touching.

Ingredients for broccoli cheese casserole

The name says it all, the main ingredients of this easy to make the dish, is the broccoli and the cheese. Fresh broccoli florets are such a breath of freshness in this casserole. Their crunchiness and vivid green color is a delight, visual, and gustative. My recommendation is to use fresh, raw florets to benefit most of this vegetable. Frozen broccoli is also an option, however, always go for fresh veggies over the frozen ones.

You can add different kinds of cheese to make the taste more complex. Parmesan is a not-to-miss ingredient, and you can play with any cheeses such as cheddar cheese or mozzarella, or pecorino. Also, to add creaminess and liquidity to the composition, you need some heavy cream. If this last one seems too fat for you, feel free to replace the heavy cream with some sour cream or greek yogurt. 

Don’t miss out on the spices to give more temper to the dish and balance the sweetness of the cheeses. Therefore, grab some salt, granulated garlic, and ground pepper.

Here’s the list of ingredients:

  • Broccoli, one medium head
  • Heavy cream 8 oz
  • Sour cream 8 oz
  • Shredded cheddar cheese, 1 cup
  • Shredded mozzarella, 1 cup
  • Grated Parmesan, ½ cup
  • Salt 1 tsp
  • Ground pepper 1tsp
  • Granulated garlic 1 tsp

How to make keto broccoli cheese casserole?

Put some water to boil in a pan and salt it. Meantime, wash the broccoli and cut its florets. Add the florets to the boiling water and let them soften a bit, that should take about 2-3 minutes. Drain the broccoli, set aside, and proceed to the next step. 

Grab your grater because you’ll have to grate the cheeses. Or, you may buy already grated cheese to avoid extra work and mess. However, I prefer to do it myself because this is how I know that I use the freshest products out there.

Once you have the shredded cheese, put in all in one big bowl, add the heavy cream, the sour cream, and all the spices. Mix everything and taste for salt and pepper. If you find it just right, add the broccoli florets and mix them again to have them well coated in the creamy mass. 

Use a medium baking pan to get the casserole cooked. There is no need to grease the walls of the baking pan because the ingredients of the dish are already very rich in fat. When the cheeses will get melted by high temperature, the fat will be released and that serves perfect to the composition not to stick to the walls of the pan.

Bake the keto broccoli cheese casserole

Preheat oven at 350 degrees for about 10 minutes. When preheating, you are sure to put the preparation at the right temperature, thus, the cooking starts immediately. This way you avoid the casserole to undergo a thermal shock that could compromise its perfect success. The better the oven is preheated, the better the results.

Bake the casserole for 10 minutes or until you see a golden top. The top becomes slightly crispy and the melted cheese is an absolute delight. 

Once the 10 minutes expire, take the casserole out of the oven and let it cool for about 20 minutes. It is an absolute must to allow it to cool down a bit, contrarily, you will get a runny mass and not a very beautiful aspect. Moreover, it will be hard to extract even portions out of the pan. Don’t forget that the keto broccoli casserole is mainly made out of different types of cheese, thus, it is a normal thing for it to need a little time to harden and get a steady shape.

After the steam has gone out and it has cooled for about 20 minutes, take a silicone spatula or a knife and cut as many portions as you like out of the casserole. Place it on a plate and serve as is.
