I'm Liam O'Connor, and I've spent years perfecting recipes that fit a low-carb lifestyle without making you feel like you're missing out. These sides are my secret weapon for keeping meals interesting and filling, whether you're serving them alongside grilled chicken, pan-seared steak, or roasted fish.
In this post, I'll walk you through two versatile sides: a creamy cauliflower mash that rivals any potato dish, and a garlicky zucchini noodle salad that's fresh and bright. Both come together in about 30 minutes, use simple ingredients, and are perfect for meal prep. Let's dive in!
Why You'll Love This Recipe
About the Ingredients
1 large head cauliflower (about 2 lbs / 900g), cut into florets
Look for a firm, white head with no brown spots. You can use frozen florets in a pinch, but thaw and pat dry before cooking.
3 cloves garlic, peeled
Fresh garlic gives the best flavor; if you only have jarred minced garlic, use 1 teaspoon.
3 tablespoons (45g) unsalted butter, plus extra for serving
For a dairy-free option, use olive oil or a plant-based butter.
1/2 cup (120ml) heavy cream
Heavy cream adds richness; for a lighter version, use half-and-half or unsweetened almond milk.
1/2 cup (50g) grated Parmesan cheese
Freshly grated melts better; pre-shredded may contain anti-caking agents. Substitute with nutritional yeast for a dairy-free kick.
1 teaspoon salt
Adjust to taste; use kosher or sea salt for best flavor.
1/4 teaspoon black pepper
Freshly ground pepper adds a nice bite.
2 medium zucchini (about 1 lb / 450g)
Choose firm, medium-sized zucchini; spiralize into noodles or use a vegetable peeler to make ribbons.
2 tablespoons (30ml) olive oil
Extra virgin olive oil adds fruity notes; any neutral oil works for sautéing.
1 tablespoon (15ml) lemon juice
Freshly squeezed is best; bottled works in a pinch.
1/4 cup (10g) fresh parsley, chopped
Flat-leaf parsley has more flavor; you can also use basil or chives.
Tips & Tricks
Don't overcook the cauliflower
Boil until just tender (about 10-12 minutes) – if it's mushy, the mash will be watery.
Dry the zucchini well
After spiralizing, pat with paper towels to remove excess moisture; otherwise, the noodles become soggy.
Season gradually
Taste and adjust salt and pepper at the end, as Parmesan adds saltiness.
Pro Tips
Step-by-Step Instructions
1. Boil the Cauliflower
Place the cauliflower florets and garlic cloves in a large pot and cover with salted water. Bring to a boil over high heat, then reduce to a simmer and cook until the cauliflower is fork-tender, about 10-12 minutes. This gentle simmer prevents the florets from breaking apart.
2. Drain and Steam Dry
Drain the cauliflower and garlic well, then return them to the hot pot. Shake over low heat for 1-2 minutes to evaporate any excess water. This step ensures a creamy, not watery, mash.
3. Mash the Cauliflower
Add the butter, heavy cream, and Parmesan to the pot. Use a potato masher or immersion blender to mash until smooth and creamy. Season with salt and pepper to taste. Keep warm over low heat while you prepare the zucchini noodles.
4. Spiralize the Zucchini
Using a spiralizer or vegetable peeler, create noodles from the zucchini. If using a peeler, make long ribbons. Place the noodles in a colander, sprinkle with a pinch of salt, and let sit for 10 minutes to draw out moisture. Pat dry with paper towels.
5. Sauté the Zucchini Noodles
Heat the olive oil in a large skillet over medium-high heat (375°F / 190°C). Add the zucchini noodles and sauté for 2-3 minutes, tossing frequently, until just tender and slightly golden at the edges. They should still have a slight crunch.
6. Finish the Zucchini Noodles
Remove the skillet from heat and toss the noodles with lemon juice, fresh parsley, and a pinch of salt and pepper. The residual heat will warm the lemon and herbs without wilting the noodles further.
7. Serve Both Sides
Spoon the cauliflower mash into a serving bowl and top with an extra pat of butter if desired. Serve the zucchini noodles alongside. Both are best enjoyed immediately, but they also hold well for a few hours.
Delicious Variations
- Add roasted garlic to the cauliflower mash for a deeper flavor: roast 5 cloves in foil at 400°F (200°C) for 30 minutes, then mash in.
- Stir in 1/2 cup of shredded cheddar or Gruyère into the mash for a cheesy twist.
- For a spicy kick, add a pinch of red pepper flakes to the zucchini noodles along with the lemon juice.
How to Store Dinner Sides Low Carb
Refrigerator
Store both sides in separate airtight containers in the fridge for up to 4 days.
Freezer
The cauliflower mash freezes well for up to 3 months; zucchini noodles are best fresh, but you can freeze them in a single layer for 1 month, then thaw and pat dry before reheating.
Reheating
Reheat the mash in a saucepan over medium heat, adding a splash of cream or milk to loosen. For zucchini noodles, warm them in a skillet over medium heat for 1-2 minutes.
Frequently Asked Questions
Q: Can I make these sides ahead of time?
Yes, both sides can be made ahead. The cauliflower mash can be refrigerated for up to 4 days and reheated; the zucchini noodles are best prepared fresh but can be stored for 1 day – just reheat them briefly and they'll be fine.
Q: What can I substitute for heavy cream in the cauliflower mash?
You can use half-and-half, whole milk, or unsweetened almond milk for a lighter option. The mash will be slightly less rich but still creamy.
Q: How do I prevent zucchini noodles from becoming soggy?
Salting the noodles and letting them sit for 10 minutes, then patting them dry, removes excess moisture. Also, avoid overcooking – they only need 2-3 minutes in a hot pan.
Q: Are these sides keto-friendly?
Absolutely! Both are low in carbs and high in healthy fats, making them perfect for a ketogenic diet. The cauliflower mash has about 5g net carbs per serving, and the zucchini noodles about 4g.
Q: Can I use frozen cauliflower for the mash?
Yes, frozen cauliflower works well. Just thaw and pat dry before boiling to avoid excess water. Reduce cooking time to 5-7 minutes since frozen florets are already tender.
