My Personal Experience
I used to throw away broccoli stems, thinking they were too tough to be useful. But once I discovered how to spiralize them into noodles, everything changed! They have a mild, slightly sweet flavor and absorb sauces beautifully. The best part? They hold up much better than zucchini noodles, staying firm instead of turning watery. Now, every time I buy broccoli, I get excited knowing I’m making the most of every part of the veggie.
Required Equipment
Spiralizer
This is the easiest way to turn broccoli stems into noodles. I prefer using a handheld one for quick jobs, but a larger countertop version works great if you’re making a big batch.
Sharp Knife
You’ll need a good knife to trim the tough outer layer of the stems before spiralizing. A sharp chef’s knife makes this process quick and easy.
Sauté Pan
A wide sauté pan or skillet is perfect for cooking these noodles. You want enough space for them to cook evenly without overcrowding.
Ingredients & Substitutions
- Broccoli Stems (2 large stems) – The star of the recipe. If you don’t have broccoli stems, you can use kohlrabi or daikon radish for a similar texture.
- Olive Oil (1 tbsp) – Helps to sauté the noodles while adding a rich flavor. Avocado oil works as a great substitute.
- Garlic (2 cloves, minced) – Brings a nice depth of flavor. You can also use garlic powder if you’re in a pinch.
- Salt & Pepper (to taste) – Enhances the natural taste of the broccoli stems.
- Parmesan Cheese (2 tbsp, optional) – Adds a nice umami boost. Omit for a dairy-free version or use nutritional yeast instead.
- Lemon Juice (1 tsp, optional) – A little acidity brightens up the flavor of the noodles.
How to Make Keto Broccoli Stem Noodles
- Prepare the Broccoli Stems – Trim off the tough outer layer of the stems with a knife or vegetable peeler.
- Spiralize the Stems – Using a spiralizer, cut the stems into long noodle-like strips.
- Heat the Oil – In a sauté pan over medium heat, add olive oil and minced garlic. Cook for about 30 seconds until fragrant.
- Cook the Noodles – Add the spiralized broccoli stems to the pan and toss them in the garlic oil. Cook for about 3-4 minutes, stirring occasionally.
- Season & Serve – Sprinkle with salt, pepper, and a little lemon juice if using. Remove from heat and top with Parmesan cheese. Serve immediately.
Tips for This Recipe
- Don’t Overcook – The noodles should be tender but still slightly crisp.
- Use Fresh Stems – Older, woody stems won’t spiralize well.
- Try Different Sauces – These noodles are perfect with pesto, Alfredo, or a garlic butter sauce.
Optional Additions
- Red Pepper Flakes – For a little heat.
- Mushrooms – Sauté some mushrooms alongside the noodles for extra texture.
- Chicken or Shrimp – Add protein for a complete meal.
Serving Ideas
- Serve with a creamy Alfredo sauce for a rich, satisfying dish.
- Toss with olive oil, lemon zest, and fresh basil for a light, refreshing side.
- Use as a base for keto stir-fries with your favorite veggies and proteins.
Storage Recommendations
- Refrigeration – Store leftovers in an airtight container for up to 3 days.
- Freezing – Not recommended, as the noodles lose their texture when thawed.
- Reheating – Quickly sauté in a pan for 1-2 minutes to warm them up.
Frequently Asked Questions
Can I use a knife instead of a spiralizer?
Yes! Just slice the stems into very thin strips using a sharp knife or a julienne peeler.
Are broccoli stems really good for you?
Absolutely! They contain fiber, vitamins, and antioxidants, making them a nutritious choice.
Can I use frozen broccoli stems?
Fresh is best, as frozen stems can be too soft to spiralize properly.
