Before starting, remove 3 tbsp butter (dbl for 4 ppl) from the fridge and set aside to come up to room temperature. Preheat the oven to 450°F. Add 10 cups water and 2 tsp salt to a large pot (use same for 4 ppl). Cover and bring to a boil over high heat. Wash and dry all produce. Heat a large non-stick pan over medium-high heat. When hot, add 1 tbsp oil (dbl for 4 ppl), then turkey. Cook, breaking up turkey into smaller pieces, until no pink remains, 4-5 min.** Season with salt and pepper. While turkey cooks, peel, then mince or grate garlic.

Add spaghetti to the boiling water. Cook uncovered, stirring occasionally, until tender, 10-12 min. Reserve 1/4 cup pasta water (dbl for 4 ppl), then drain and return spaghetti to the same pot, off heat.

While spaghetti cooks, add mirepoix, half the garlic and 1 tbsp butter (dbl for 4 ppl) to the pan with turkey. Cook, stirring often, until mirepoix softens slightly, 2-3 min.

Stir in crushed tomatoes, cream, broth concentrate, balsamic glaze and reserved pasta water. Season with salt and pepper. Bring to a boil over high. Once boiling, reduce heat to medium. Cook, stirring occasionally, until sauce thickens slightly, 4-6 min. Remove the pan from heat. Add 1 tbsp butter (dbl for 4 ppl) and spinach. Stir until spinach wilts, 1-2 min.

While sauce cooks, combine remaining garlic and 1 tbsp butter (dbl for 4 ppl) in a small bowl. Season with salt, to taste. Halve ciabatta. Arrange on an unlined baking sheet, cut-side up. Spread garlic butter over ciabatta. Sprinkle cheese onto top. Bake in the middle of the oven until cheese melts, 1-2 min. (TIP: Keep an eye on them so they don't burn!)

Add sauce to the pot with spaghetti, then toss to combine. Divide spaghetti between plates. Serve cheesy garlic toast alongside.
