SARA’S NOTES

casserole dish baked perfectly with golden brown on top

The casserole I made on a Sunday meal prep day with my husband, and it did not disappoint. We used cashew almond milk to create the creaminess, used lactose-free cream cheese, and loaded it up with spinach and broccoli. It came out incredibly delicious, creamy, rich, and deeply satisfying. Best part? The leftovers might be even better. If you're cooking for a crowd or meal prepping for the week, this one is a keeper. 🌿

  3. Melt butter in a large skillet over high heat. Add sliced mushrooms and diced onion. Cook, stirring occasionally, until the onion softens and the mushrooms begin to brown. Add broccoli florets and cook about 2-3mins, add spinach last, until wilted.

  4. Remove from heat. Add shredded chicken, softened cubed cream cheese, and remaining ¼ cup of milk. Stir until the cream cheese is fully incorporated and the mixture is creamy.

  5. Add the skillet mixture to the baking dish (with the rice mixture) and stir gently to combine everything evenly.

Macro breakdown using the magic plate formula

🌿 WHY THIS NOURISHES YOU

Rotisserie chicken is one of the most convenient and complete sources of lean protein available, making this a genuinely high-protein, satisfying meal that supports muscle repair and keeps you full for hours. The wild rice blend brings together complex carbohydrates for steady, sustained energy alongside a gentle hit of fibre. Mushrooms are rich in B vitamins and immune-supporting compounds, while broccoli delivers vitamin C, folate, and powerful antioxidants. Spinach wilts seamlessly into the creamy sauce, quietly adding iron, magnesium, and a boost of nutrients without changing the flavour at all. Cashew almond milk keeps it light and creamy without any of the lactose and the result is a dish that feels indulgent while nourishing your body deeply. Leftovers keep well in the fridge for 4–5 days and reheat well.
