It’s gluten-free, vegan, vegetarian, paleo and Whole30.
Lightly Boiled Asparagus
Asparagus is a fantastic vegetable – full of hormone-balancing nutrients, fibre and antioxidants – and it’s especially lovely in season. It’s also very pretty with its pointy, dragon skin like spears and looks great with bright colours.
One of the easiest ways to prepare asparagus is boiling it, which sounds super boring but what I mean by that is ‘a lightly boiled asparagus’. You essentially want to blanch the vegetables to heat them through but to retain some of the crunch and that gorgeous green colour. Boiled asparagus can be a great base for something exciting!
Once it’s done, serve it right away with a delicious sauce such as my Spanish red pepper sofrito.
Sofrito Of Red Bell Peppers & Onions
Because asparagus itself has a pretty neutral flavour, it’s a great vehicle for sauces and punchier ingredients such as hollandaise, garlic aioli and so on.
I thought it would work really well with slowly cooked onions, bell peppers and garlic, and the olive oil infused with the flavours of those foods. This mixture is also known as sofrito and is the base of Spanish paella.
Sofrito takes 10-15 minutes to cook so that vegetables can soften and caramelise, giving you the most delicious umami sweetness.

I wanted to keep it as a vegetarian and vegan asparagus recipe but if you are an omnivore, you can add bits like chopped chorizo or bacon to the cooking sofrito mixture. Both work really well with asparagus.
What To Serve With Asparagus
Enjoy this dish warm or cold, and use it as a side dish with any main. It would go well with fish, chicken or any meat or as a colourful potluck dish at a dinner party.
For a vegetarian or vegan meal, serve this asparagus dish with quinoa or brown rice and lentils or with some plant-based burgers or sausages. It’s also lovely as is with some toasted sourdough rubbed with garlic and drizzled with olive oil.
PS. Leftovers are great in an omelette!

Loving the look of this vibrant and nutritious side!
Um, where did you add the lemon?
Drizzle over at the end, it’s optional. I will clarify in the instructions 🙂
Quite good but I found that adding some Chorizo (mild) and smoked paprika took it to the next level.
