My Favorite 20-Minute Dinners for Weeknights

By Lindsay Metternich | Harmony Helpers

We’ve all had those nights—when you look at the clock, it’s already 5:30, and you realize you forgot to thaw anything, plan anything, or even think about dinner. I’ve been there more times than I can count.

That’s why I’ve built a little secret weapon:

A rotation of 20-minute dinners that are fast, tasty, and kid-approved.

These aren’t fancy. They don’t require weird ingredients.They’re just real food for real families—made fast.

Below are five of my absolute favorites, plus the grocery list you’ll need to knock them all out in one trip.

🍝 1. Creamy One-Pot Pasta with Spinach & Parmesan

Why I love it: One pot. No straining. Everyone eats it—even the picky ones.

• 1 clove garlic, minced

• Salt and pepper to taste

Instructions:

1. In a large pot, add pasta, broth, garlic, and a pinch of salt.

2. Bring to a boil, then reduce to simmer until pasta is tender (about 10–12 minutes).

3. Stir in milk and spinach. Simmer until spinach wilts.

4. Add Parmesan and stir until creamy. Serve warm.

Optional add-in: Rotisserie chicken or frozen peas

1. In a skillet, warm tortillas with cheese and chicken inside. Fold and cook until golden on both sides.

Make it faster: Use microwave rice packs or frozen pre-cooked rice.
