Butternut Squash Kale and Farro Casserole
Butternut squash, kale, and farro casserole turn simple winter vegetables, hearty grains, creamy beans, and nutty Gruyère into a cozy dinner that feels special without costing much.
This is the kind of from-scratch meal I make when I want something filling, colorful, and practical. The squash roasts until sweet at the edges. The kale softens into the warm farro. White beans add creamy texture and extra protein. A bubbling layer of Gruyère brings everything together with a golden, savory finish.
Why You’ll Love This Recipe
- Cozy and hearty: Farro, beans, and roasted squash make this casserole feel like a full meal.
- Big flavor from simple ingredients: Garlic, onion, thyme, and Gruyère add deep savory flavor without a long ingredient list.
- Naturally balanced: You get fiber, plant protein, leafy greens, and slow-digesting whole grains in every serving.
- Great for leftovers: The casserole reheats well for easy lunches or a quick second dinner.
Fabian’s Budget and Health Tip: Buy a whole butternut squash instead of pre cut cubes when you have a few extra minutes. It usually costs less per pound, and you can save the seeds to roast with a little salt. If Gruyère feels pricey, use half Gruyère and half sharp cheddar to keep the nutty flavor while lowering the cost.
Ingredients Serves 4
- 4 cups peeled and cubed butternut squash, about 1 3/4 pounds (800 g)
- 2 tablespoons olive oil (30 ml), divided
- 1 medium yellow onion, diced (150 g)
- 3 garlic cloves, minced (9 g)
- 4 packed cups chopped kale, tough stems removed (120 g)
- 3 cups cooked farro (540 g)
- 1 can white beans, drained and rinsed, 15 ounces (425 g can, about 240 g drained)
- 1 cup low-sodium vegetable broth (240 ml)
- 1 tablespoon fresh thyme leaves or 1 teaspoon dried thyme (3 g fresh or 1 g dried)
- 3/4 teaspoon fine salt (4 g), plus more to taste
- 1/2 teaspoon black pepper (1 g)
- 1 cup shredded Gruyère cheese (100 g)
Step-by-Step Instructions
1. Roast the Squash
Heat the oven to 400°F (200°C). Place the cubed butternut squash on a baking sheet. Toss it with 1 tablespoon olive oil, 1/4 teaspoon salt, and a pinch of black pepper.
Roast for 22 to 28 minutes, stirring once, until the squash is tender and the edges look golden and slightly caramelized. The sweet roasted smell should be noticeable before you pull it from the oven.
2. Cook the Onion, Garlic, and Kale
While the squash roasts, warm the remaining 1 tablespoon olive oil in a large skillet over medium heat. Add the onion and cook for 5 to 7 minutes, stirring often, until it turns soft and lightly golden.
Add the garlic and thyme. Stir for about 30 seconds, just until your kitchen smells fragrant. Add the chopped kale and cook for 3 to 4 minutes, until the leaves turn glossy, darker green, and slightly wilted.
3. Combine the Casserole Filling
Grease a 9 by 13 inch baking dish or a similar casserole dish. Add the cooked farro, drained white beans, roasted squash, and the kale mixture.
Pour in the vegetable broth. Add the remaining salt and black pepper. Stir gently so the squash stays mostly intact but everything gets coated. The mixture should look moist, not soupy.
4. Top with Gruyère and Bake
Sprinkle the shredded Gruyère evenly over the top. Bake at 400°F (200°C) for 18 to 22 minutes, until the broth bubbles around the edges and the cheese melts into golden spots.
Let the casserole rest for 5 minutes before serving. This short rest helps the farro soak up the last bit of broth, so each scoop holds together better.
Expert Troubleshooting and FAQs
Do I need to cook the farro before adding it?
Yes. Use fully cooked farro for this casserole. Dry farro will not soften enough in the short bake time, and it will absorb too much broth.
Can I use frozen butternut squash?
Yes. Roast it straight from frozen if the pieces are already cubed. Give it a little extra space on the pan so it roasts instead of steaming. It may need 5 to 8 more minutes in the oven.
Why did my casserole turn out dry?
The farro may have been very firm or the casserole may have baked too long. Add an extra 1/4 cup vegetable broth (60 ml) before baking if your cooked farro seems dry. The filling should look lightly moist before the cheese goes on.
Can I make this ahead?
Yes. Assemble the filling up to 24 hours ahead, cover it, and refrigerate it. Add the cheese right before baking. If baking from cold, add 5 to 10 minutes to the bake time.
What can I use instead of Gruyère?
Sharp cheddar, Swiss cheese, fontina, or a mix of mozzarella and Parmesan all work. Gruyère gives the deepest nutty flavor, but these swaps still melt well and taste great.
