Chef Jenn’s Tips To Make This Keto Asparagus Recipe

  • Use fresh asparagus and beans! Frozen just don’t turn out as nicely, especially frozen asparagus!
  • Green or yellow beans will work fabulously in this dish.
  • Don’t have shallots? Substitute about 1/3 cup chopped green onions instead.
  • Add a pinch of crushed red pepper flakes to add a bit of heat to this keto side dish recipe.
  • If you’ve salted the veggie boiling water and used bacon, there should be plenty of salt in this dish. But you can always taste a bit to adjust, and add a few cranks of fresh black pepper.
  • To make this dish ahead, make all the parts. Boil the veggies, fry the bacon, and make the sauce. Chill the veggies quickly in an ice bath. To serve it, reheat the veggies with a quick dunk into boiling water or heat them in the microwave. Reheat the sauce and finish the dish as usual.

What To Serve With Keto Asparagus & Green Beans with Lemon & Pecans

This is a lovely side dish that pairs well with just about any roast. Go for my famous keto beef pot roast, or opt for a juicy and tender keto pork roast recipe.

Is This Keto Green Been Recipe Freezer Friendly?

Sure, you can freeze it but be warned that the veggies won’t be quite as crisp and fresh after freezing, and the nuts will lose their crunch.

That being said, if you want to freeze this dish, chill it thoroughly in the fridge then package it in air-tight zipper-top bags or freezer-safe containers.

To eat, thaw first then heat it gently in the microwave.

Is asparagus keto?

Yes! Not only is asparagus a really nutritious veggie, it has plenty of fiber and is low in carbs which makes it a great keto pick.

Are beans keto?

If they’re green or yellow beans (not legumes), then yes they are! Green beans are a bit higher in natural sugars (carbs) so you don’t want to feast on them, But in moderation they’re just fine!

What vegetables are keto?

Cabbage is a great keto vegetable, as is zucchini, broccoli, cauliflower, and more!

    You had me at Bacon! This was super easy. I was out of pecans so I subbed in some roasted peanuts and it was delicious.

  2. 5 stars
    Green beans are my favorite veggies. I left the bacon off of this because I’m vegetarian, but the veggies were delicious. And cooked perfectly!
