Instructions

Crafting this casserole is a rewarding process, building layers of flavor and texture with each step.

1. Preheat your oven to 400°F (200°C). This initial high heat is crucial for softening the butternut squash efficiently.
2. Prepare the Butternut Squash: Cut one of the butternut squash halves lengthwise. For the second butternut squash, peel it and then cut it into 1/2-inch cubes. This dual approach ensures both a creamy, mashed base and tender, distinct pieces within the casserole.
3. Roast the Halved Squash: Coat a nonstick cookie sheet with cooking spray. Remove the seeds from the squash half you cut lengthwise. Place this half, cut side down, onto the prepared cookie sheet. Roast until very soft, approximately 35 to 40 minutes. The goal here is to make the flesh incredibly tender and easy to mash. Once roasted, remove it from the oven and allow it to cool.
4. Sauté the Mushrooms: While the squash is roasting, heat the olive oil in a large nonstick skillet over medium-high heat. Add 2 chopped garlic cloves. Swirl the skillet to mix the garlic into the oil and cook until fragrant, about 10 seconds. Be careful not to burn the garlic.
5. Cook the Mushrooms: Add the sliced white button mushrooms and 1/4 teaspoon of table salt to the skillet. Increase the heat to high and cook, stirring often, for 6 minutes. This high heat helps to brown the mushrooms and evaporate excess moisture, concentrating their flavor.
6. Combine Mushrooms and Cubed Squash: Remove the skillet from the heat and stir in the cubed butternut squash. Let this mixture cool.
7. Prepare the Creamy Base: In a medium saucepan, combine the fat-free evaporated milk, sliced shallots, the remaining 2 chopped garlic cloves, and the chopped fresh sage.
8. Simmer the Base: Bring this mixture to a boil, then cover the saucepan and remove it from the heat. This allows the shallots and garlic to infuse their flavors into the evaporated milk.
9. Mash the Roasted Squash: Once the roasted squash has cooled enough to handle, scrape the flesh of the roasted squash halves into a large bowl. Mash the squash using a potato masher until mostly smooth.
10. Incorporate the Creamy Mixture: Add the milk mixture (including the shallots, garlic, and sage) to the mashed squash in the bowl. Mash again to thoroughly combine everything. This creates the luscious, binding element of the casserole.
11. Season the Squash Mixture: Season to taste with salt and pepper. Remember that the mushrooms are already seasoned, so taste before adding too much additional salt.
12. Assemble the Casserole: Coat a 9×9-inch pan with cooking spray. Spoon half of the mashed squash mixture into the bottom of the pan and spread it into an even layer.
13. Layer the Noodles and Mushroom Mixture: Top the mashed squash with 3 uncooked lasagna noodles. You will likely need to break them to make them fit the pan. Spoon 1 cup of the mushroom-squash mixture evenly over the noodles.
14. Repeat the Layers: Top with 1/2 cup of the mashed squash mixture. Repeat the layers one more time: 3 uncooked lasagna noodles (broken to fit), another 1 cup of the mushroom-squash mixture, and finally, 1/2 cup of the mashed squash mixture to finish.
15. Bake the Casserole: Cover the pan with foil. Bake for 20 minutes. This initial covered baking time allows the noodles to soften and absorb moisture from the squash and mushroom layers.
16. Finish Baking: Remove the foil and bake for 10 minutes more. This uncovered period allows the top to slightly crisp and meld.
17. Rest Before Serving: Remove the casserole from the oven and let stand for 10 minutes before slicing into 6 pieces. This resting period is essential for the casserole to set, making it easier to slice and serve cleanly.

Expert Tips & Tricks

• Don’t Overcook the Garlic: When sautéing the garlic initially, watch it closely. It’s meant to become fragrant, not brown or bitter. A quick 10 seconds is usually sufficient.
• Mushrooms: Size Matters for Sautéing: Slicing the mushrooms thinly ensures they cook down evenly and release their moisture effectively within the 6-minute cooking time.
• Noodle Integrity: Breaking the lasagna noodles to fit is perfectly fine and necessary for an even distribution. Don’t worry about perfect shapes; they’ll soften and meld into the casserole.
• Seasoning is Key: Taste your mashed squash mixture before assembling. Adjust salt and pepper as needed. Remember that the evaporated milk can sometimes mute flavors, so a good seasoning here is vital.
• Make-Ahead Magic: The mushroom mixture and the mashed squash mixture can be prepared a day in advance and stored separately in airtight containers in the refrigerator. Assemble and bake just before serving. You may need to add a few extra minutes to the baking time if assembling from cold ingredients.

Serving & Storage Suggestions

This Butternut Squash, Sage and Mushroom Casserole is a star on its own, but it also pairs beautifully with a crisp green salad dressed with a light vinaigrette or a side of steamed green beans. For a more substantial meal, consider serving it alongside grilled chicken or fish.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat individual portions gently in the microwave or oven until warmed through. Freezing this casserole is possible, but the texture of the noodles might be slightly softer upon reheating. If freezing, allow it to cool completely before wrapping tightly in plastic wrap and then aluminum foil. Thaw overnight in the refrigerator before reheating.

• Gluten-Free: For a gluten-free version, use gluten-free lasagna noodles. Ensure they are suitable for baking and follow the package instructions for cooking time, as they can vary significantly.
• Vegetarian Powerhouse: To make this even more hearty and protein-rich, consider adding cooked lentils or crumbled firm tofu to the mushroom mixture.
• Herb Swap: While sage is divine here, other herbs like thyme or rosemary would also complement the earthy flavors beautifully. Use them in similar quantities.
• Spice It Up: For a touch of heat, add a pinch of red pepper flakes along with the garlic when sautéing the mushrooms.

FAQs

Q: Why is the butternut squash roasted in two ways?
A: Roasting one half until very soft allows for a creamy, mashed base, while cubing and sautéing the other adds tender, distinct pieces of squash throughout the casserole.

Q: Can I use dried sage instead of fresh?
A: Yes, you can substitute dried sage, but use it sparingly as it is more potent than fresh. Use about 1/3 the amount of dried sage to fresh (roughly 1 teaspoon of dried sage).

Q: What if I don’t have whole-wheat lasagna noodles?
A: You can use regular lasagna noodles, but they may contribute more in terms of points and carbohydrates. Whole wheat provides a good dose of fiber.

Q: Is it necessary to let the casserole rest after baking?
A: Yes, resting is crucial. It allows the casserole to set and firm up, preventing it from falling apart when you slice and serve it.

Q: Can I make this casserole ahead of time?
A: The mushroom and mashed squash mixtures can be made a day ahead. Assemble and bake just before serving for the best texture and flavor.
