A note about serious food allergies
The warmth and ease of a casserole meets the subtle and classic flavors of French onion soup in this baked pasta dish. First, you'll caramelize the onions and brown the mushrooms, then mix them with pasta, cream, and thyme, layering flavor upon flavor. Finally, you'll top the casserole with croutons and cheese (just like the soup!) and bake. Richly cheesy and perfectly indulgent, this dish might even top the classic it was inspired by. Tip: Easy way to remove thyme from stem: just pinch the top and run your fingers down the stem. Presto! The leaves should just fall off.
Due to our just-in-time sourcing model, we may have to send you a

Meatlovers! Cook proteins in a medium non-stick pan over medium heat. If using diced chicken, pat dry and season all over with a pinch of salt and pepper. Stir occasionally with 1 tsp. olive oil until chicken reaches minimum internal temperature, 5-7 minutes. If using steak strips, separate into a single layer and pat dry. Stir occasionally with 1 tsp. olive oil until no pink remains and steak reaches a minimum internal temperature of 145 degrees, 4-6 minutes. Add to penne as desired.
Prepare the Ingredients
Cut mushrooms into ¼" slices.
Halve and peel onion. Slice halves into thin strips.
Coarsely crush croutons.
Cook the Mushroom-Onion Mixture
Place a large non-stick pan over medium-high heat. Add 2 tsp. olive oil, mushrooms, onion, garlic, ½ tsp. salt, and ¼ tsp. pepper to hot pan.
Stir occasionally until onion and mushrooms are deep brown, 10-12 minutes.
While mushroom-onion mixture cooks, cook pasta.
Cook the Pasta
Once water is boiling, add pasta and cook until al dente, 10-12 minutes.
Drain pasta in a colander, shaking to remove as much water as possible. Set aside. Reserve pot; no need to wipe clean.
Make the Pasta Mixture
Return pot used to cook pasta to medium-high heat.
Add cream, vegetable base, half the thyme (reserve remaining for garnish), half the mozzarella (reserve remaining for topping), cooked pasta, and mushroom-onion mixture to hot pot. Stir to combine.
Bring to a simmer. Once simmering, stir occasionally until slightly thickened, 2-4 minutes.
Remove from burner.
Bake Casserole and Finish Dish
Pour pasta mixture into prepared casserole dish. For best results use an 8" casserole dish. Top with crushed croutons and remaining mozzarella.
Bake in hot oven until cheese is golden brown, 10-14 minutes.
Plate dish as pictured on front of card, garnishing with remaining thyme. Bon appétit!
