Lemony Asparagus & Cauliflower Casserole Recipe

This cauliflower casserole is a family favorite!

The first time I made this, I gave a piece of asparagus to my dog Sunny. She ate it! This is when I learned that asparagus is the only vegetable she eats out of my hand. I tried a green bean – nope. She spits out every vegetable, even carrots. But she LOVES asparagus.

Asparagus is a nutritional powerhouse, making this cauliflower casserole super healthy!

  • Asparagus contains vitamins A, C, E, K, and folate.
  • It’s also a great source of fiber and folate, an important part of the B-vitamin group.
  • Asparagus is a natural food source of glutathione, our body’s master antioxidant. Although most of the body’s glutathione is produced by the liver, asparagus is the food source with the highest concentration, followed by avocado and spinach.

This spring vegetable is delicate and should be eaten within 48 hours of purchase. When cooking it, if steaming or sautéing keep it under 3 minutes for maximum nutrition, color, texture, and flavor. You could also simply blanch it (plunge it into boiling water followed by a cold water rinse).

When I first made this recipe I loved it instantly, especially with the strong lemon flavor (I used extra by mistake and it worked well). I used lemon juice blended with the organic lemon peel. Lemons (including the fiber and peel) have many health benefits:

  • Lemons are high in vitamin C, which is not only important for heart and immune health, but essential for healthy skin.
  • The pectin (mostly in the peel) may help you feel fuller, longer. The vitamin C in lemons can also help reduce cravings.
  • Some studies suggest lemons may help prevent weight gain by improving blood sugar and insulin levels. The pectin is a soluble fiber that can slow down the digestion of sugars and starches.
  • Lemons contain antioxidants to support overall health and have antibacterial properties.

I have modified this asparagus & cauliflower casserole over the years (mainly added a lot of lemon) and this version is what I am currently using. Oh, and you can use more asparagus than the recipe indicates. Enjoy.
