| Step | Description | Tips |

| 2. Prepare meat sauce | Heat 1 Tbsp olive oil in a large pot over high heat. Brown the sausage for 5-8 minutes, add onion and cook for 2 minutes. Reduce heat, stir in crushed tomatoes, 1 cup water, bay leaf, oregano, salt, and pepper. Simmer for 15 minutes until thickened, then mix in the roasted garlic paste and adjust seasoning. | For a smoother sauce, stir occasionally while it simmers. |
| 3. Prep squash | Poke each spaghetti squash with a fork and microwave for 3 minutes (or halve, seed, and pre-roast cut-side down for 15 minutes at 425°F). Cool slightly, cut lengthwise, and scoop out seeds. | If you’re short on time, the microwave hack works wonders. |
| 4. Cheese mixture | In a bowl, combine milk, ricotta, nutmeg, basil, salt, and pepper. Fold in 1 cup Fontina and 1/2 cup provolone. | Fresh basil really brightens this up pick some from your garden if you can. |
| 5. Assemble | Place squash halves in a baking dish, season cut sides with salt and pepper, and sprinkle the remaining Fontina inside each half. Spoon the meat sauce evenly over the squash, then dollop the ricotta mixture on top. Finish with the remaining provolone and cover loosely with foil. | Layering is key for that gooey cheese effect. |
| 6. Bake | Bake for 20 minutes covered, then remove foil and bake an additional 15-20 minutes until the squash is tender and the cheese is golden. Let rest for 5 minutes, then scrape the flesh into strands, mixing with the sauce and cheese. Garnish with thyme or fried sage if desired. | It smells amazing when it’s done wait a few minutes before digging in.
