How to Make Keto Vegetarian Roasted Butternut Squash with Chimichurri

This recipe has two simple parts: the roasted squash and the chimichurri. Both are low-effort, high-reward, and come together in under an hour.

What You'll Need

For the roasted squash:

• 1 medium butternut squash, halved lengthwise and seeds removed
• 2 tbsp olive oil
• 1 tsp smoked paprika
• ½ tsp garlic powder
• Salt and black pepper to taste

For the chimichurri:

• 1 cup fresh flat-leaf parsley, packed
• ¼ cup fresh cilantro (optional but chef's kiss)
• 3–4 garlic cloves
• ½ tsp red pepper flakes
• 3 tbsp red wine vinegar
• ½ cup extra virgin olive oil
• Salt to taste

Step-by-Step Instructions

Step 1: Preheat your oven to 425°F (220°C). High heat is non-negotiable here — it's what gives you those gorgeous caramelized edges.

Step 2: Prep the squash. Score the cut flesh in a crosshatch pattern (about ½ inch deep). This helps the seasoning penetrate and speeds up cooking. Brush generously with olive oil, then sprinkle with smoked paprika, garlic powder, salt, and pepper.

Step 3: Roast it. Place cut-side down on a parchment-lined baking sheet. Roast for 35–40 minutes, flipping cut-side up for the last 10 minutes. You want fork-tender flesh and slightly golden edges.

Step 4: Make the chimichurri. Pulse parsley, cilantro, garlic, and red pepper flakes in a food processor. Add vinegar and olive oil, then pulse again until combined but still a little chunky. Season with salt. Done. Seriously, that's it.

Step 5: Serve and drizzle. Plate your squash halves and spoon that glorious green sauce right over the top. Trust me on this one — be generous.

Tips for the Best Results Every Time

Fair warning: once you nail this, you'll be making it on repeat. Here's how to make sure it's perfect:

• 🔪 Don't skip the scoring. It's the difference between “pretty good” and “oh wow.”
• 🌡️ Use a hot oven. 400°F minimum. Lower temps make the squash steam instead of roast.
• 🫙 Make chimichurri ahead. It actually gets better after sitting for 30 minutes as the flavors meld.
• 🥗 Bulk it up. Serve over a bed of arugula or alongside roasted cauliflower for a more filling keto vegetarian meal.
• ❄️ Meal prep magic: Store roasted squash in the fridge for up to 4 days. Chimichurri keeps for up to a week.

Serving Ideas That Make This Feel Extra Special

This dish is already beautiful on its own, but here are a few ways to take it further:

• Add a protein: Top with a fried egg or crumbled feta for extra staying power.
• Go full bowl: Serve over cauliflower rice with extra chimichurri drizzled on everything.
• Dinner party ready: Plate individually with microgreens and a lemon wedge — crowd-pleaser alert, your guests will ask for the recipe.
