Time
1 hour 15 minutes
Ingredients
1 medium spaghetti squash (about 2 1/2 lb.)
1 tbsp. neutral oil
1 3/4 tsp. (or more) kosher salt, divided
6 oz. broccoli, cut into 1" florets (about 1 1/4 cups)
1 tbsp. plus 1/4 cup water, divided
3 tbsp. unsalted butter
1/2 yellow onion, finely chopped
3 garlic cloves, minced
1 tbsp. all-purpose flour
1/2 c. whole milk
4 oz. cheddar, shredded, divided (about 1 cup)
Instructions
Step 1
Arrange a rack in center of oven; preheat to 400°. Cut spaghetti squash in half lengthwise. Scrape out seeds. Rub inside of squash with oil; season with 1 tsp. salt. Arrange cut side down on a baking sheet.
Step 2
Roast squash until tender and browned, 35 to 45 minutes. Let cool slightly.
Step 3
Meanwhile, in a medium heatproof bowl, season broccoli with 1/4 tsp. salt. Pour 1 Tbsp. water into bottom of bowl. Cover and microwave 1 minute. Stir and continue to microwave in 30-second increments until broccoli is bright green and fork-tender, 30 seconds to 1 minute more. Uncover and let cool slightly.
Step 4
In a large skillet over medium heat, melt butter. Add onion; season with 1/2 tsp. salt. Cook, stirring occasionally, until onion is tender and sweet to the taste, 7 to 8 minutes. Add garlic and cook, stirring, until fragrant, about 1 minute more. Add flour and cook, stirring, until a bubbling paste forms on bottom of skillet, about 1 minute more.
Step 5
Slowly whisk in milk and remaining 1/4 cup water. Bring to a simmer over medium-high heat and cook, stirring occasionally, until thickened, 1 to 2 minutes. Remove from heat and fold in 3 oz. cheddar until a smooth sauce forms; season with salt, if needed.
Step 6
Using 2 forks, shred spaghetti squash strands from shell. Measure out 3 cups and transfer to skillet; reserve remaining squash for another use. Add broccoli to skillet and toss to coat in sauce.
Step 7
Return cheesy spaghetti squash to squash shells. Top with remaining 1 oz. cheddar.
Step 8
Heat broiler. Broil squash, watching closely, until cheese is melty and blistered on top, 1 to 2 minutes.
